I'm going to do a group project on my own forcing my partner to do it alone
Why would you not want to do it with your partner?
I think my partner is overcomplicating the project
I understand how you think your partner is overcomplicated things, but you are expected to work together in group projects. What kind of message is that sending to other people? You should try and really work together and overcome conflicts.
Bitch I'm lazy and high on marijuana. I'm eating chips go away
I do not think that it is responsible of you to be high on marijuana while doing a group project. Your partner is leaning on you to do your best with this project and your grade also depends on this so I do hope you be sober and finish the project as soon as you can.
