BD 4 takes dance classes one day a week and has her first recital coming up. We were talking about it last night and SD15 got all snippy because she thought the recital had already happened. "Thanks for inviting me," she said sarcastically. OK, am I missing something? SD never comes to BD's class unless husband brings her along. She doesn't watch BD dance and has not come to either of the two classes where parents and families were encouraged to watch the kids.

Plus, and this is much bigger, SD has not come to a single one of BD's birthdays. In four years! She is always invited (I even send an invitation to her in the mail so it seems more official). She always has an excuse not to come.

So why does SD want to complain about the slight of not being invited to BD's dance recital? It hasn't happened yet, so husband told her the date, even though we both know she won't come. Any ideas what's going on here?
