My face muscle was laughing to ache today

It's a happy day in classroom, my face muscle feels ache because of the crazy laughter with my classmates.
Caiqi is more and more aggressive in recent days, does not show any respect to any one and have bacome the president of our gangster IG instead of Shaun absolutely. I laugh at her when she is attacking other ones, but I feel deeply pain when she is attacking me and other ones are laughing at me.
Shaun's handphone is likely to lose at anytime when he puts it on the table, it even disappeared in front of his eyes, driving him crazy. It's alway a long way to find it out.
Angela asked us to draw a poster for a promotion of the cellphone, everyone likes a captious consumer in the presentation and does not give up any chance to accuse each other especially our team because there is no 0 button in our design!
Went Orchard Road with Yewjinn and Farhan after class, all of us are bored. I want to buy a new dangler but cannot find a nice one.
Tomorrow half of the class will stay in school overnight, we planed it from last week, it would be a great night, haha.
