What if I say my partner didn't do anything in a subtle way during the project presentation?
Are you joking? Did your partner really not contribute at all?
He did not, I did all of the work myself
Not having all partners contribute to a group presentation is unfair. Bring up the issue directly, so there is not misunderstanding and so you don't seem passive aggressive.
Everybody should know. He is a slacker.
But by being subtle, they might not understand the signal. It would be faster and more clear to just say what the problem is to your teacher and to the other student.
