DEAR MISS MANNERS: I ran into a co-worker whom I had not seen in 25 years. The nature of our jobs did not require much interaction, and I considered her an acquaintance rather than a personal friend.

We acknowledged each other by name, then she immediately commented, “You look different.”

I managed a weak joke about my gray hair; however, I felt the comment was rude and insulting. Unfortunately, I was stuck in an elevator with this person and had to continue the awkward conversation until we reached our destination. I believe that one should refrain from making a comment about someone’s appearance, especially someone they hardly know. You do not know their circumstances and risk treading on an individual’s privacy.

Do you think her remark was rude? How would you suggest replying to a practical stranger saying that you look different than you did 25 years ago?

GENTLE READER: “Well, yes, it’s been 25 years. I’m sure we both do.”
