What did you do with your townies? Are there any you especially like or dislike?

As I usually play University, my Sims usually end up falling for and moving in/marrying a random they meet in their dorm or on a community lot. It's not going so well for Marla Biggs right now. She is still single and about to graduate so maybe the next time I play her in a different neighborhood, something will happen (I am playing in Riverside right now).
