Well, yes, if you had not interupted, i was going to say that this isn't really because i'm a "nice" person. It's more like i enjoy having the responsibility and mantle of being host so in a way it's a selfish desire. On Friends, Phoebe and Joey were trying to figure out if there were any nice deeds that didn't involve self pleasure. Like anything good you did was partly out of a "wow, i'm such a nice person" motivation. I mean, i feel that's very true. People are motivated by only their own selfish goals (not to use selfish in the traditional "evil" light, just selfish as in self serving).
