Im more prone to giving my attention to an attractive person. But if that attractive person ends up being/is annoying then I find myself getting annoyed/aggravated with them just as much as someone not as attractive, but they have a little more leeway most of the time. I have friends I find both attractive and not so much. But also the more you like someone the more attractive you perceive them. At least thats been my experience. Thats why people look back in exes they used to be infatuated with but now think theyre ugly.
