What are your thoughts on me telling my flatmates I'm leaving? I'm actually going to convince the owner to kick them out!
This sounds like a mean thing to do. Do their parents not come around much?
Their parents do not come around at all.
If you are having a disagreement with your flatmates, it isn't appropriate to try to get them kicked out unless you or your property is in physical danger. Instead of trying to get the owner involved, you should try to resolve your differences peacefully and constructively. Moving requires a lot of time and expense and should only be considered as a last resort.
I can't stand these losers anymore. I need to take drastic measures to get rid of them.
It's natural to have disagreements with your roommates from time to time. However, getting them kicked out is wrong. It's best for you to talk with them about issues you may be having.
