I don't know it gives much more behind the other post, by I use to call my self the smilling girl. It sounds stupid but I think I smille most than the majority of people. It was cute when I was a kid, a shy smiling girl. I don't find it cute or nice now. Once a teacher asked me "she smiles a lot, doesn't she?" and a "friend" answered instead of me something like this. "She smiles a lot some times, and other times she's way to quiet". Well that teachers said I would had wrinckles if smilling so much...Maybe it's a defense, a nervous one, a way of act when you don't know how to act and how to feel.
