My friend's sister is getting married in a couple weeks, and the bachelorette party is this weekend. I am not invited to this wedding, as I'm not that close with the girl but am good friends with her sister. My friend invited me to go float the river with them for the bachelorette party. I said no, I'm not crashing your sister's B-party, and didn't hear much about it for awhile. Well she just called me this weekend and told me again that she really really wanted me to come float the river with them and that her sister said it was fine and that it wasn't a big deal, there were a big group of girls going. So I said ok we'll see, and now she's telling me how she's so excited for it, but I still feel kind of awkward about it, if that really is the B-party. Would you go?
