Answer:
i understand that when you're frustrated you tend to not think in your actions, but you could've thought it through before throwing your glasses on the table. Your parents worked hard to get you the glasses, and glasses are pretty expensive. i do admit your parents are in the wrong too for hitting you for just having trouble with an assignment and getting frustrated. it sounds like your dad is pretty abusive, if he does this regularly with no reason at all, please do seek help.
