其实， 我发现很多中国小孩有这样的习惯。
如果 我小的时候需要每天上课12个小时我回家也很累。太可怜！
hope you can understand my poor Chinese ;-)
For me, when I was at school I never had anytime to eat! At break and at lunch times I would rush straight out to play football. So by the time I got home I was starving! I would make myself dinner at about 4pm then when my parents came home from work, I'd eat a 2nd dinner and probably have a snack before bed too!
