DEAR ABBY: I'm a college junior in need of advice. I share an apartment with two other female students, "Wendy" and "Lauren," who roomed together before I met them. Wendy is sweet and easygoing, but she grew up in a rural area and seems very sheltered. For example, she can't swim and thinks that eating shrimp is exotic, but she likes to clog dance and play the mandolin. She has never mentioned having a boyfriend or even dating. We are completely different, but until recently we got along well.
