SIMiLING (the new confusion)

So my college has a high married student rate. So as i have been gaining experience in the college life i have learned the first thing i do when i look at a girl is shoot my eyes at the left ring finger. ( i must say i have gotten really good at that) then i judge them if they are pretty or not if they dont have a ring on. pretty much. but lately these girls have done one of two things to me well maybe three. first let me say i am generally a happy person who listens to music as he walks and laughs out loud for no apparent reason even when know one else is there walking with me to school. so its safe to say i always smile. well lately ill be walking and smiling at the same time( its not as easy as it sounds or looks(I dont know which one)) anyways i smile at these girls and guys ( i guess) and these girls think i am hitting on them like a creep. so some smile back and giggle and chat to their stupid friends others sneer and make fun and think i am extra creepy, well let me just say this if i were to like u i would do something way creepier than smile to let u know that i would evesdrop on a conversation get your name and maybe follow a bit with out you knowing get info on you then facebook stalk you and send a creepy request with an even creepier message so there u go! take that girls i smile at!
