I am going to submit this piece of work on my own behalf instead of giving my partner credit.
Did your partner and you do equal amounts of work?
Well they actually did most of the work.
If your partners did most of the work on your project, then taking credit without them will upset them greatly and make you look like a bad person. You should instead go back and revise your work to reflect everyone's contribution on the final product.
They didn't give me credit in the first place. I'm getting passive aggressive with them.
While it is annoying that they weren't giving you credit in the first place, does that not upset you? Why would you want them to feel that same anger and disappointment?
