I am home now and check out the wifi , it took me nearly 15 minutes ,maybe  I need to force myself to go to sleep earlier which will make body more comfortable and more healthy . last night i went to sleep at four in the morning and got up nearly at twelve . i seldome do such a thing like that . just forgot the time  ... but i can finished my daily works .  i yawned while  on bus home but i didnot fall asleep .... haha . i even rang to lin in order to keep awake , but not for long . bcz talking on the phone on bus or in public place is bad manners to your friend who is speaking to you and as well consider the passengers around you on bus

ok , take a bath and go to sleep   !
