I already suspect the only reason she hangs out with me and my other 2 friends is because I've been letting her copy my math homework since this school year began. I get A's in math meanwhile she struggles with low B's and C's. Math isn't for everyone. Understandable.
Though it's getting kind of tiring always having to hand her my homework. I took my time and energy on those exercises (not my fault I had natural skills for numbers) and she just copies from me every single time we got algebra II.
Or for the sake of keeping her friendship, should I continue letting her copy? I don't have too many friends anyways.
