Yeah, the whole "... I'll have a drink a bit later" thing is slightly annoying but I generally don't get pressed about it.
For me, I'm a 'don't, don't tell' type of gal by default so my band (my buddy Herby) is my business. If down the line I get questioned about my scars I'll say I had a procedure done. If the conversation goes further, maybe I'll disclose more info (depending on the type of relationship) but I personally don't think it's anyone's business.
However, if I end up in a situation where there's a potential for a serious relationship, then I'll mention 'Herby' if the topic comes up.
