go to bed..............

i used to sleep about 8-9 hours each weekday(monday-friday). although critters claim that for children below 12 is around 10-12 hours .i can't say that i do not have enough sleep as i have been sleeping about 8-9 hours each weekday from about 5 years old because my parents need to work.i do not sleep early because my parents usually'bug' me to learn my english and chinese spelling. i think people can have enough sleep by sleeping before 10 'o clock.
