Another eye contact question... between acquaintances?

Anonymous
Saw a couple of questions posted recently about eye contact, and got to thinking. If a guy I don't know makes eye contact with me, I consider it a pretty good indication that he's interested in me (and assume he does the same for me). What about with girls you do know, though? If you like a girl in one of your classes, at work, or that you're friends with, do you make a lot more eye contact with her when you're talking with her than you do with other people? If so, why?
