Only if they give me something back in return. jk jk
I do if they need the help or don't understand a question.
I remember I helped my "now friend" out with a question at the TAFE here
and the teacher we had lashed out at me....
She was from out of town and weird so.... eh.... (I was annoyed but only for a little while).
so homework copying can only get you so far, before someone randomly gets mad. (from personal exp).
