The truth is, sometimes we (parents) just don't get it. It's sad, but true.

If you can't talk her into going, fine. Go, play your little heart out, then go home brag about how incredible you were. (I'm sure you're incredible all the time. ) Make her really wish she hadn't missed it. Maybe that'll make her want to go to the next one so she doesn't miss anything.

Either way, I'm soirry this is happening to you. It does suck, it's not fair, and you have every right to be upset.
