Why do mothers let their kids do this?

Shouldn't she be learning how to clean house, do dishes, cook, or play with Barbie dolls instead of wasting her time playing this crap? She is 10 years old and she writes fusion but can she play "Smoke on the Water"? Her mom should send her to her room instead of letting her humiliate guitar players all over the world. Maybe we could play like that if we had a guitar like hers.
