I'm not gonna list a group member's name on our lab report. Is that sneaky?
Depends on the context. Why aren't you?
He did most of the work, but I want all the credit.
That isn't cool. You should be honest and not take credit for something someone else did.
I don't care, it's none of your business. What I do is none of your business.
I'm certain you know that what you're doing is wrong. You need to include their name instead of lying.
