i am sooo careless...

heyz, tian ping here. when you were leaving our last class last friday, maths, did anyone see a stack of envelopes in the classroom?? I've lost my teacher recommendations from Mr Karamjeet... Or did anyone see me with the envelopes at any point later, when we were at 1U? for the life of me I can't figure out where I lost them at all! Augh... Come on, work those memories, if I don't get them back I'm going to be in serious trouble >_<...
