Roommate didn't pay rent on time... late fee is 100$ ... it's bad enough he asked us to borrow 500$ dollars... now that makes it 600$... I only have 1200... rent is now 1200$ .. I can't do this shit... I'm so stressed... he's really plucking my last nerve.. you don't know how bad I want to knock him on his ass and just strangle the fuck out of him... and no, it's not the hormones. I swear. I just don't like him. he's fucking irresponsible.
