not a happy day

i hope i could be happy every day, but this is an imperfect world, i am not happy today. i think i am not lucky today.
the first class is MGX 9230, i planed listening carefully this class, so i sit in the first row, just oppostie the desk of teacher. but after the class began, i felt so so so tired, i wanted to sleep, but i can not, because i just faced to the teacher. OMG, i think everyone can imagine this, want to sleep, but can not. i was so daez in the first half of the lecture, i am not sure what teacher teached, but according to the lecture, it seems not so hard. i am not quite sure. and the bad news is i just review the lecture notes, and can recall nothing. i had a nap during the break. and felt better when i got up. the teacher talked about the assignemnt, that is i really care about, and then teacher said blah blah blah, i can not remeber...but the most important sensenses were: there is not one way to fail this unit, that is u hand in nothing ... i am so happy to hear that. UH OH. after that, a case study was conducted, i did not read the case previously, i was so lost in the second half of lecture...what a pity...
about AFF 5100, the tragedy repeated. i do not want to recall it. but i still learn one thing, i do need to watch the book before the lecture.
OK, so much for today...i need to study harder and harder...
