I'm not going to help my friend on a test
Why don't you want to help your friend?
Because I'm a fucked up person who doesn't like helping others.
Wow, that's hardcore. In my opinion it's always best to help your friends out when possible.
I agree but I'm too lazy to help him. I can do it if I really wanted to but I don't feel like it.
Keep your laziness aside and help your friend in need. It will make your friendship stronger and I'm sure he'll reciprocate your gesture.
