hi!
please excuse me but i've got to state: i am only being nice because i want something! i can't think of a single person in history who was nice, and was nice without wanting anything from it. for example, one person would probably go through their life trying to be nice to each person they encountered no matter what, because by doing so it might be helpful or make things better somehow. so of course you'd only be nice to someone because you want something!
anyway, have a nice day!
