I'm a college student at a pretty big college, so I walk past plenty of hot girls every day. If I see an attractive girl I usually try to make eye contact and smile. The smile usually ends up being a toothless grin, because it feels awkward to me to smile with teeth to someone who is just walking by. Does anyone else know what I'm talking about? Do you guys smile with or without teeth to girls walking by?

(I know this seems like I'm focusing on inconsequential minutia, but I just wanted to get some other opinions.)
