Lan si ex-group mate

Slept at 10 plus last night..had a bad headache..woke up at 7 plus this morning to finish up my tutorial work for this week and last week. Had 2 tutorials this morning, 1 at 9am and the other one at 10am. After the first tut, my friends and i were walking to E&B for the next tut, met a ex-group mate from last semester services marketing group assignment. He didn't border to say hi or even a smile on us. (the other 2 frens walking with me were in the same group as well) Perhaps he didn't see me, but it is quite impossible that he didn't see three of us...unless he is blind...Really worry about my 2 presentations and 1 report due next week. We haven't start doing anything for the report the due next friday...worry X 99999
