All smiles

Lately I've been challenging myself to smile at everyone that passes me by during the day. Everyone. Not just my clients or the crazy looking girl who rings me up at Wal-mart, but everyone. And I've come to find that most people do not want to be smiled at. When I smile at most people they look at me like I am wearing a dead gazelle carcass. Or, they simply act as though I never smiled and them and actually they weren't looking at me at all, even though I know they were looking at me. Why is this? I don't understand. Here I am trying to be a nice person who isn't socially awkward and I get these strange looks in return. Are there really that many people in the world that don't smile, that when they are smiled at they think it's odd? Am I really socially awkward and am wrong to think that smiling might help someone's day out? I don't know. But I will continue to smile at everyone, because it gives me warm fuzzies inside, and maybe eventually mankind will catch on.
