Those tags about "CB",i'll tell you what it means...
In our chemistry lesson,our teacher,Mrs Ng gave us one paper with "Chemical Buddies" written bigbig on top. Bottom got alot of chemicals. For each chemicals,we have to write a friend's name. Everyweek Mrs Ng will choose one chemical and we have to see that chemical she choosen is who,and we have to sit with him/her.
So for the first lesson,she choosen 'carbon buddy'. So my 'CB' (carbon buddy,and now u know what CB,me and wanqian talking about!HAHAH!) is karen,and wanqian's abigail. So we called them CB,and started saying "CB,u got alot hair leh!" , "CB,u're bleeding!!" , "CB,dont run away from me!!" ,and so on. HAHAHAHAHAHHAHA!

So that's all.. We are not talking about that cb,is this CB. LOL!
