Dear Carolyn: A few years ago, I got very chummy with an old acquaintance. We knew each other socially for years, but the closeness is new.

She can be a fun person . . . shopping trips, meeting for coffee, etc.
I allowed it to grow into a lopsided arrangement where she calls every few days to check in, shares facts and gripes about everyone in her life. At a recent luncheon, she blurted out — to people I don’t know — a few things about me that I shared with her. It finally dawned on me that this is part of her DNA. She just can’t keep anything private.
