I wear a crocheted wristband that I made some time ago pretty much all the time... It isn't anything particularly special, but it has a number embroidered on it that is significant to me. I wear it as a reminder.
If ever anyone asks about it, I just say that the number is significant to me, but doesn't mean anything to other people, and leave it at that.
Yesterday, shortly after I was introduced to a friend of a friend, I was again asked about it - so I gave my standard answer. This woman would not let it go! She got quite irate when I wouldn't explain it fully to her - but frankly, she is a stranger to me and I will likely never meet her again. I could not see why she had to know, and her reaction was bizarre.
So, AIBU not to share the significance of it? It is personal (just a 3 digit number, not a date or anything) - and she didn't have a need to know.
Should I just hide the wristband away too, or answer anyone who asks?
