hi! nice to see you :) i study chemical engineering too! :D agree with you on snail mail :)

Hey! How have you been doing lately? Are you still working till late hours :D? We could do some text chat or even video chat on Skype in Japanese, although your level is probably better than mine, it's always fun. Especially that I have quite a bit going:D
