Can anyone tell me what is the defination of best friend/ good friend?

Okay, superteen tmr.
Lilian tells me how much i'll be motivated to get 7A1s for O's.
And i tell her the motivationn will last for 2weeks only la.
Haha i heard it was fun& all from stanley& many but they motivate you by guilt which jiancong says is a bad thing and not a right way.

Hmm i'm not very very excited bout it cause of the longggg hourrrrrs.
Ok but i hope i'll enjoy and get motivated?
