<human>: I have recently moved into a new apartment and the neighbor below me seems to have an issue with the noise that I make.  
The problem is when they are knocking I'm either not making any noise, or it is the middle of the day.  I have called in a few different complaints about them but it seems they have done the same to me and my apartments are siding with them at the moment. The complaint they keep giving is that there is a knocking sound( Similar to a headboard hitting against the wall.) coming from up here a lot. 
 Ok, so the issue is with me.  I take down the headboard re-arrange my room to make sure I keep the noise down.  

So now no headboard.  I'm sitting on my bed reading a book around 1 am.  Knocking on my floor because of noise(I assume)  I do have a roommate but she is asleep(no headboard) my girlfriend is on the bed with me.  No noise we talk every once in a while, but because of our fear of getting another complaint we whisper and tip toe around the house at night.  I understand not being loud and being respectful of the people around me but this is getting to be ridiculous.

  I mean some times at 5 pm they will knock on my ceiling for noise.  I'm not loud even during the day.  I have been woken up while sleeping because of the knocking because of my alleged noise I'm making.  I'm tired of walking on eggshells and it is driving me up the wall.  Let's not forget the fact that I NEVER see anyone leave from that downstairs apartment.  Ever.  I see lights on in the building sometimes but I've never seen anyone enter or exit.  I need some advise.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Evil neighbors are complaining to the apartments that I am making too much noise at night(and apparently at times when I am allowed to make noise) even though there is no way I'm making noise.
