Can I resent my flatmate over a stupid mistake?
I want to know the circumstances of the incident. Tell me more.
They kept bothering me while I was trying to study for my exam.
They shouldn't have bothered you. But you shouldn't resent them for it, since it sounds like this isn't a reoccurring problem.
It happens every day..
Wow, that sounds quite annoying. I see where you are coming from now. I think you should consider moving out and getting a new place since this kind of distraction is going to make your grades fall eventually.
