You must be so proud.
My daughter just did her Grade 7 French Horn exam, sings in the Australian Girls Choir and has no interest in anything percussive - despite being told by her choir conductor that she's a born percussionist. (That's after she was chosen to play the clave part to accompany the choir when they opened the Australian Pavilion at Expo in Shanghai.
The older daughter writes songs, sings, plays guitar and violin - but also has no interest in drumming. She doesn't even want me to drum on her recordings!
Tough life, isn't it?
