I'm not going to tell a university class when classes are or when assignments are due as a class rep.
That's your job why won't you tell them?
I'm being a slacker and just don't care anymore.
That is your job as class rep. You should let them know about their assignments and not be lazy.
I am doing the best I can and don't understand why you are bothering me when I don't care.
Why did you take the job if you weren't going to do it. You need to fulfill your responsibilities.
