DEAR ABBY: My husband and I are retired. A short while ago, a young couple moved in across the street. A few months later, my husband, who does yardwork for neighbors for extra money, started working in theirs. He never charged them for it, and even after they had the equipment to care for their yard, continued working there some of the time.

When "Cindy," the wife, would be in the front yard, he frequently stopped his work to talk to her or stare at her. (He never stopped his work for anyone else.) Several times a week, I'd notice he was over at Cindy's mowing the yards on each side of her house and would make excuses to check to see if anything else needed to be done. He confessed to me about looking through the fence one time, and I'm sure he has done it more.

One day, I caught him standing, fixated, watching her work in the front yard, completely oblivious to his surroundings. He has told me how pretty he thinks she is, and she IS attractive. She rarely starts a conversation or comes into our yard, but he goes into hers to talk at every opportunity. If I question him about it, he either lies to me, laughs at me or yells at me. What should I do? -- HUMILIATED IN TEXAS

DEAR HUMILIATED: Your husband obviously has a crush on this young, pretty neighbor. Fortunately, from what you have written, it doesn't appear to be reciprocated. If I were you, I'd develop a sense of humor about the situation. Tell him that if he's planning to run away with her, you want advance notice so you can call your lawyer. Then bide your time because these kinds of crushes usually wane.

DEAR ABBY: A good friend of mine borrowed $5,000 because she said she was going to nursing school. I happily loaned it to her, but discovered later that she unenrolled several days after classes started. I asked her for the money back, but felt sorry for her because she was not working due to the pandemic.

Fast-forward a year: I have extensive dental work scheduled, so I finally asked her to repay me. I told her I would take payments, but I need a regular time of month, every month. She agreed to pay me back but made no mention of a timeline.

I am not sure how to approach her again. I'm not rich, and she knows it. We even shook hands on the agreement with her telling me she'd pay me back at a date that has now passed. Advice? -- TOO GENEROUS IN OREGON

DEAR TOO GENEROUS: You are learning a very expensive lesson. With "friends" like this woman, you do not need enemies. Do not count on getting any money from her. Find another way to pay for that dental work because, without a repayment agreement IN WRITING, there's no way you can force your "good friend" to do the right thing. Something to keep in mind for the future: Do not give anyone any more money than you can afford to lose.

DEAR ABBY: I'm a senior in high school, and I come from a family that is financially stable but unable to travel often due to time and money constraints. We usually travel only once a year in the summer, and for the most part, we're not able to travel very far or stay for long.

For the past three years, our vacation plans have been on hold due to the pandemic and other concerns. My parents have been on two trips across the country in the past 12 months. I accept that they're a married couple and occasionally want to travel without the rest of their family. However, recently it came to my attention that Mom bought two tickets to Europe for her and Dad as a birthday gift. She used the money she had been saving for a family vacation to pay for them.

I feel betrayed. I was under the impression that we couldn't afford a vacation at this time, or that we were still waiting for the chaos of the pandemic to settle before traveling, but my mother was happy to spend the money on a vacation for her and Dad.

My dad is turning 50, and I understand it's a very special occasion. However, I can't help but wonder why I haven't received so much as a dinner after being accepted into my top college and earning two scholarships. Am I overreacting? If not, how should I address this? -- WANTING A GETAWAY IN NEW YORK

DEAR WANTING: I agree that having been accepted to your top college and having earned two scholarships, your achievement was something to be celebrated. (In reality, the achievement was a reward in itself.) That it was not recognized tells me there must be a lot going on for your folks right now.

While family vacations are wonderful and memorable, so are milestone birthdays such as the one that's approaching for your dad. Your mother should be forgiven for ensuring it will be "extra special." If you feel an itch to travel, if you don't already have one, consider getting a part-time job so you can afford a getaway with friends or a student or church group. Because you are no longer a child, you should talk to your mother about how you feel.

DEAR ABBY: My adult son got so furious with me that he called me, yelled vicious things and threatened to cut me out of his life. I've never been spoken to that way before. It was so traumatic that I was shaking after I hung up on him.

What made him so angry was that I didn't thank his mother-in-law for an email she sent wishing me happy birthday. I had received 30 email birthday wishes that day and didn't acknowledge any of them. I would have thanked someone who'd gone to the trouble of calling or sending an actual card. I don't think I behaved improperly, but maybe there's some rule that slipped by me. Your thoughts? -- UNHAPPY BIRTHDAY IN TEXAS

DEAR UNHAPPY: The polite way to deal with email special occasion wishes is to either acknowledge them individually or do an email "blast" thanking everyone for remembering you. To have remained stone silent was ungracious. HOWEVER, for your son to have gone off the deep end, yelled "vicious things" and threatened to cut you out of his life was uncalled for, and whether or not you receive one, you deserve an apology.

DEAR ABBY: In my junior year of high school, my girlfriend got pregnant. We married and had a son. Although our marriage was very rocky, two years later we had a daughter. I knew from the beginning she was not my biological child because of her blood type, but I loved her all the same. I never told my daughter or my ex-wife (now deceased) what I knew. Four years after her birth we divorced, and I retained custody of my two children.

I later remarried and had one more child. Fifty years have now passed. With DNA testing being so prevalent, I'm at a loss. Most of my family (my parents, children, grandchildren and great-grandchildren) have been tested and show up linked to me.

My daughter, her children and grandchildren do not show up anywhere on my DNA chart. They live 2,000 miles away, but we communicate weekly. I am sure that she and some of her family have been tested and "suspect" but are saying nothing to spare my feelings. I feel I need to clear the air with my daughter, but my wife says to let sleeping dogs lie. Advice? -- OLD DOG IN THE WEST

DEAR OLD DOG: I agree with your wife. You raised your daughter, and she is as much your child as if she had "come from your loins." You ARE her dad. IF she or one of her family members has been DNA tested and she hasn't broached the subject with you, it may be because she has no questions she wants to ask you. I see nothing to be gained by raising the subject now.

DEAR ABBY: I'm writing in response to "Paying Respects in California" (Feb. 19), the married man who wondered if it was weird for him to attend the funeral of an old school friend (female) and to go alone.

At my mother's funeral (our father had passed years before), a few of my mom's old school friends, male and female, showed up and stopped to tell us how they had gone to school with her and wanted to pay their respects. One gentleman said he went on a few dates with her. Another confessed he had the biggest crush on her in school.

Whether they had wives at home or not never crossed our minds at the time. We were just so touched that they came, and that after all these years she still meant something to them. And we loved hearing about the crush. We were so happy and tickled to hear these stories about our school-aged mom at a time when our hearts were broken because of her loss.

Yes, "Paying Respects" should go to the funeral. I am sure her family will appreciate it. -- BILLIE JO IN NEW JERSEY

DEAR BILLIE JO: Thank you for your letter. Your sentiments were echoed by many other readers. One commented that she attended the viewing of a former co-worker she wasn't close to ONLY out of respect for his mother who was still alive. Others expressed experiencing a sense of closure from reconnecting with the family and friends of someone they knew in the past.

DEAR READERS: Along with the millions of Americans who are observing this Memorial Day, I am adding my prayer of thanks for those courageous men and women who have sacrificed their lives in service to our country. May they rest in peace. -- LOVE, ABBY
