DEAR ABBY: I have a job I love. My co-workers are nice, but once I punch out at the end of the day, I want to forget them. I believe that's how it should be, but some of them try to arrange meet-ups after work to hang out. Or they insist on becoming my friend on social media. I don't consider them social friends, and I don't think they need to know the details of my private life. Is there a nice way to tell these people to back off a little because we only work together? -- NINE TO FIVE IN NEW YORK
DEAR NINE TO FIVE: When you are invited to hang out after work, explain that you have things you need to do or previous commitments. And as for sharing your personal information with them online, all you have to say is that you prefer to keep your business and personal lives separate.
