stay up late is really bad!!!!! After i finished my college entrance exam,i was free,i needn't to do the math exercise at least 3 months,i needn't to get up before 6:00 in the morning,i really like the feeling,and so my classmates,we singing songs in the KTV,after some crazy night,we began to play at home.I stay up very late,i watched movies,played computer games,sometimes me and my friends hung outside very late,i think now that i have passed my exam,i needn't to be a father and mother's baby,they can't asked me to do anything anymore.But after somedays i found my eyes was like pandas......my skin became drier,its a nightmare for a girl.........after i finished my tour to yunnan with my friends,i was totally tierd and slept all day ........ STAY UP LATE IS REALLY FOR ONE'S HEATH,i never want to do that anymore............
