DEAR SOMEONE ELSE’S MOM: Right after my college graduation I moved back home. While I was away at school my parents started using my room as a guestroom when my grandparents and aunt and uncle came to visit. Now that it’s my bedroom again my mom is on me, like always on me, to clean it up. I’ve got all my stuff from my old apartment, plus all the stuff I purposely left behind when I went off to school.

I know it’s messy, but isn’t it my room to keep the way I like? --- Messy in MARYLAND

DEAR MESSY: You may be on the right track, but you’re at the wrong station.

It is your room, but it happens to be located under your parents’ roof, which means it’s subject to their house rules.

You complain about all the stuff you have, to which I say, whose fault is that? The solution is simple: Eliminate, eliminate, eliminate.

Start with the remnants of childhood, but first let Mom and Dad do a little souvenir hunting. If they want to preserve your t-ball participation trophy and your first soccer cleats, let them. Such objects are as much a part of their past as yours.

After they make their picks, pack up those precious mementos and hand them off to your folks to store in the family vault (for us it’s the attic or “memory boxes” in the basement).

This way, when you go to clean out the house in a few decades, you get to enjoy seeing fragments of your earlier days. You can share them with your own kids, giving them a chance to make as much fun of you as you did of your parents when they showed the teenage you their high school yearbooks.

Next, take a good hard look at what you hauled back from college. I’ll bet you’ve already emotionally and physically outgrown at least a fraction of it. Allow yourself a few pieces of memorabilia to entertain future generations. Tidily box up your treasures and shove them to the back of your closet or under your bed, to be reclaimed when you have a place of your own.

Now you’re ready to sort through the rest of your clutter.

If you can’t see yourself using the thing you just shook the dust bunnies off of in the next couple of years, then wash it, bag it, and deliver it to your local thrift store.

Remember to ask for a receipt. Even if you can’t use it for your taxes, your parents might, even under the new tax regulations. Think of it as a small repayment for all the storage fees they never charged for yourself or your stuff.

DEAR SOMEONE ELSE’S MOM: My great-grandmother made it to 103. When she passed, my mother and grandmother went kind of nuts with their grief.

I think making it to that age would have been thought by them as being kind of cool, but they only get more upset when I say anything like that to them.

Why don’t they see it as a good thing to have had my great-grandmother around for as long as she was? --- DON’T GET THE GRIEF

DEAR DON’T GET THE GRIEF: Although it’s getting to happen more often, passing the century mark is indeed still a remarkable achievement.

Please be patient and gentle with your grieving relatives. To you, your great-grandmother was most likely always an old woman. But to your mom and grandmother, she was undoubtedly a very different person, and a constant in their world. To those who knew and loved your great-grandmother all their lives, from childhood into adulthood, and even into middle and old age, the loss is substantial, and it’ll take some time to adjust to not having her around anymore.

DEAR SOMEONE ELSE’S MOM: Please help. I’m asking advice about whether to interfere with the way my grandchildren, ages 9 and 7, are being parented. I’ve witnessed my daughter-in-law (DIL) undermine my son many times. He says no to something, and she gives it to them anyway. I say nothing.

My 9-year-old granddaughter has some behavioral issues, and they often complain about it. I found out recently that they took away a gift I gave her for Christmas (as a punishment) and planned to donate it. The rationale from my DIL was that they wanted to take away something that was meaningful. I said nothing.

Most recently, I was there for a (safely distanced) birthday dinner for my DIL. She found some paint on an upholstered dining chair and went into an all-out rage at my granddaughter. It was an accident. All of their chairs are upholstered, and my granddaughter loves to paint. My granddaughter was crying hysterically, left, and went upstairs to her bedroom. My DIL then justified her behavior to my son and he said, “It’s okay babe. I understand.” I said nothing.

You can probably guess that I’ve seen my DIL lash out at him also. I say nothing.

My ex-husband was verbally, emotionally, and physically abusive. I don’t get involved with my son’s marriage or comment on how he is being treated, even though it’s hard to stay quiet. However, I’m having a difficult time with the most recent event. My son comforted his wife. No one comforted the 9-year-old. It’s messed up.

To be fair, my DIL did apologize to my granddaughter during dinner. It was a half-baked apology. One that started with, “I’m sorry, but…” I said nothing.

My son and the grandkids are being verbally and emotionally abused, as I see it. What advice do you have? --- CONCERNED GRANDMA

DEAR CONCERNED GRANDMA: Parenting a child with behavioral issues can be a challenge for the calmest of parents. If your daughter-in-law tends to be high-strung and demanding, it sets the stage for an even more difficult time, and may be contributing to the behavior.

My hope is that what you see is only part of the childrearing conversations between your son and his wife. In any case, it’s unfortunate when one parent contradicts the other in front of the children. Inconsistency can be a dangerous thing, especially if a child is already struggling emotionally or developmentally. This may be what the children have come to expect, and your stepping in to offer criticism or advice stands a good chance of backfiring in any number of directions.

You didn’t mention if your abusive ex-husband is also your son’s father. If so, your son should have a good sense of the effects of that type of personality on a whole family. He may be thinking that keeping the peace with his wife is one way to avoid further tensions in front of the kids. They’re old enough, though, to be aware of who’s calling the shots, and that may be why they try to go around Mom through Dad.

As painful as it may be for you to witness, I believe you’re right to continue your non-interference policy with your son’s and daughter-in-law’s marriage and parenting style. However, that doesn’t necessarily mean you can’t discretely remind your son of how difficult it can be to live with someone with a dangerously short fuse, since you’ve been there, done that.

Once the world’s more open again, and if it’s something you’re able to do, what might help is frequently offering to take the children out of their house. Time away from a tense home could be a big help for all involved — especially if the kids know there’s a safe haven available to them, run by a supportive, loving adult.
