Emotions:
Mr Chan is very lame but funny. Here's one of the questions in his worksheet:
a)Shan and Jol are good friends(it's quite obvious lor and he still say what i never put their full name?!hehe). One day, they quarelled at Shop A along Orchard Road(why would we quarrel in a shop at orchard road?). Jol cired(haha?!) and started running with a constant acceleration of 1.0 m/s^2(people tell story where got give what acceleration one?). After that, she ran at a constant speed for another 10s. She later decreases her speed uniformly for 10s and stopped at the bus-stop B. She waited for 10s before boarding the bus. Sketch the speed-time graph and distance-time graph for Jol.

b) Shan was stunned for 20s(stunned for 20s, imagine stand there the mouth open for 20s, lol!) when Jol started running. She didn't know what to do. She decided to chase after her at a constant acceleration of 1.4 m/s^2 for 10s and then ran at the constant speed for 10s until she reached the bus stop B. Sketch Shan's speed-time graph and distance-time graph on the same axes above.

Can Shan catch Jol on time before she boards the bus?

So this is seriously quite funny:)

Ok... this part a bit wrong. So lunch was at board room for briefing for those who not goig obs in march but in june. So during march, when almost everybody is at obs, i'll be stuck in sch. When i'm bored and feel like sms-ing someone, i realised that everyone's away. when i want to go online and talk to people, i realised that they're not online. When i go to sch, i don't see the usual people. ERIMEPHOBIA! phobia of loneliness:(
