Help: What to do with La Fiesta Tech/Strangetown sims?

I made my own Uni Sims visit those other college towns and search out partners or friends from those. You know, like real life where you are friends with others from other colleges. I liked that Sim (can't remember his name) who was in La Fiesta (the rich kid) and played him one time, but I would make him have friends with those in the other towns. You can freely visit the other college towns' community lots.
