So about 5 years ago, a coworker of mine was getting married. Another coworker (I think she was a bridesmaid or something) decided to throw a bachelorette party for her, and invited a bunch of us that were not invited to the wedding (myself included) on top of some folks who were going to the wedding. So, the arrangement was going to a restaurant and then going to a club afterwards to go dancing, etc. So, before we left dinner, people had gifts for her except for a few folks. (I just had a card and a gift card inside for her). I remember the person who hosted the 'party' was all disappointed that a good portion of us didn't bring in gifts and stuff (like boxed gifts). I remember feeling little down because of that, but in looking at the etiquette boards now and stuff, in a way, I wasn't obligated to bring anything.
I know it's like a thousand years later, but can I walk away now knowing that I probably didn't have to gift anything, particularly since we all paid for her dinner? Or should have bought something from her registry?
