If our DD11 still liked her, I'd probably take her. Just me (or her Dad) and her. DD11 doesn't like her anymore though. She's moved onto the Jonas Brothers and has her first crush on Nick Jonas.
If there were a High School Musical event, I'd probably take DD13. But, she just mentioned last weekend that she was "so over" Zac Ephron.
Moral of the story -- don't buy the tickets unless you know your kid is still going to like her on October 5. Kids are fickle these days!
Since it's going to charity, is it a tax write-off?
