I have a friend who I'm pretty close to but not close enough to ask her to be in the wedding. Every time I've seen her since I've gotten engaged she's initiated conversations about my wedding. She always asks questions like "where are WE staying?" "what are WE eating?" we, we, we. Aka- assuming she's invited before getting an invitation. And she's right, she was invited, but still. Given her presumption, I assumed she'd be coming.
I invited her to the bachelorette party. As we're talking about that, I asked her if she got the wedding invitation since she hasn't RSVPed yet. She replied, "yeah, sorry, I won't be able to make it to the wedding. It's just a lot of money to spend for one weekend."
All I could do was shake my head and laugh a little.
