So I love my bridesmaids.  All of them.  And I really love my family.  Here's my problem:
One of my bridesmaids (who I admittedly haven't known for a super long time, but is best friends with one of the other bridesmaids who I DO know really well) is going through a rough patch.  She has to work ridiculous hours and is tired all the time, and as a result gets kind of snappy and sensitive.  I totally understand why she would be like that considering the circumstances (and she and I had to have a discussion about her extrapolating something that wasn't even CLOSE to being there and getting offended - that convo went well).  Here's a problem that I'm not sure how to figure out.  At my bridal shower, she was sitting at the table in front of my cousins.  I've known these people literally my whole life.  I know how they are.  Sarcastic and super friendly.  They're not even CLOSE to being rude, or b*tchy to someone they don't know.  She complained to our mutual friend (the othe bridesmaid) that one of my cousins had said something to her in a rude way at the shower.  Mind you, she said that this was said to her when our mutual friend happened to have stepped away.  So there were "no witnesses".  My friend gave me the scoop about what the bridesmaid's side of the story was.  I don't know who said it, but hearing all of the details i would be willing to bet vital organs that it was just a joke that was taken completely the wrong way.  I spoke to the BM about it saying I was sorry that she had felt offended and I was sure that the person who said it was not intending to be rude and more than likely just joking around with her (all of my cousins BTW said how much they like ALL of my BMs when i saw them after the shower - without me asking).  I told her that I've known them my whole life and that they're just not that type of people (but again apologized that she felt hurt by what was said).  She doesn't remember who specifically said it, so I can't approach that person.  When I told her that I didn't think it was meant that way, she rolled her eyes and told me she's not stupid and she KNOWS when people are trying to be rude on purpose. I don't want anyone to feel hurt, but I know it's her being sensitive and I'm not sure what to do at this point.  I dont' want either drama OR hurt feelings at the wedding reception. What do I do?
