like attracts like

like attracts like

People tend to seek out or be attracted to those that are similar or like-minded. I guess I shouldn't be surprised that John wants to find other Americans to hang out with. Like attracts like, after all. I know that like attracts like, but you should try associating with people with some more diverse perspectives on life.
