You know... your behaviour is your fault, at all times.... you can't choose how you feel about something, but you can choose how you act. So if you choose to break things, that is your fault, not someone else's. Don't blame them for your irresponsible/destructive choices.

Really sucks about your mum though. Mine was the opposite in regards to the dentist though - I spent months as a kid asking to go and it took that long before they finally took me! I think we'd been learning about dental health in school and I wondered why I didn't ever go to the dentist. haha.
