Dear children upstairs: I’m sorry your parents are in the unfortunate situation of only being able to afford a two bedroom apartment to fit all four of you and themselves – it really is no concern of mine; but, if you don’t stop stomping, screaming, chasing, jumping or any other sort of athletic or vocally straining activity I will jump though the ceiling and put my foot in your mouth. Thank you.
Dear parents of children upstairs: Control your children. They are deafening. We need to sleep. Respectfully yours, those below you.
