early sleeping policy

okay, my dad implemented the "early sleeping policy" because of the following reasons:
1. we sleep too late that we wake up in the afternoon (during vacations), he said, "what will happen if we sleep at 3am during a school night?LATE.
2.we, well i, sleep more than 10 hours a day so if i sleep at 11pm and will wake up at 5am, it wouldn't be enough for me and i will have a hard time waking up. so you see, this policy is implemented on me because i'm the one who has earlier school hours than my brother. this sucks.
