<human>: I've recently moved in to my first (rented) flat, and am having some issues with the people in the flat above me.  I'm a light sleeper at the bet of times, and they are so damn noisy.  They have screaming children which commence at around 7am, and the parents themselves are prone to bizarre actions (playing the same few bars of piano music, rearranging furniture, using power tools, generally shouting) until 2am.  By chance the person living next door to me is a friend of a friend, and has informed me that the people in the flat above are known for being quite odd.  So, what do?  I don't want to be the passive-aggressive note leaving neighbor, but at the same time I would pussy out of a face to face confrontation.  Letting agents are useless at the best of times, plus I am not even sure if they own the flat above also.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Neighbors are loud, don't want to leave passive aggressive notes, too much of a pussy to confront them, wat do
