“Enough is enough!!!
I’m tired of this.
You’ve been partying after 10 o’clock several times the past year.
I’ve been overlooking this but last time my door-mat disappeared and that was the last straw. Return it at once! Or else I will take legal actions!”
Ask yourself: who the heck keeps his door-mat outside in the corridor when living in a student-apartment?
Yeah, you take legal actions. I quite like my new door-mat.
