So.
I have this friend. She and I used to be best friends in middle school, and she formed a special relationship with my parents during that time. She moved across the country a couple years ago, and now I only really talk to her about once a year. My current best friend and I met because we are both mutual friends of hers. Best friend talks with her much more frequently. I could include a bunch of other details, but they really don't matter. Bottom line is that while my best friend is one of my bridesmaids, this girl is not. She actually didn't even cross my mind in the list of choices. As soon as I got engaged, she decided that if my best friend was in the bridal party, then of course she was going to be one. She called my best friend and mentioned repeatedly how she couldn't imagine not being chosen. Well, she found out through the grapevine that she was not a bridesmaid. She told my best friend that she was so hurt she didn't hear it from me. What was I supposed to do, call her up randomly (which I never do), and say, "Hey, just in case you think you're a bridesmaid, you're not."? So now she's called me, and left a message saying she wants to chat. What the heck am I supposed to say when she asks why she's not a bridesmaid? Oh, and yes, she is the type to ask.
Short version: Not-so-close friend is hurt she isn't a bridesmaid. I didn't give her a reason to believe she would be. What do I say when she asks why?
