Pay the 5 days rent. You would have to pay any other place where you stayed 5 days over (sometimes for the whole month or two weeks). Yes it is petty. He shouldn't have been allowed to move in early or he should pay 1/2 the 5 days because he was there too, but it's not worth the hassle. Don't pay the fees. He would have to pay those moving in whether you moved out on time or or not. Pay him for his food you ate. Unless he ate some of yours, then forget it. Wireless internet, forget it. He has to pay the same regardless if anyone uses the signal unless you agreed upon sharing in advance.
