Lol, you do this to yourself. Nobody is holding a gun to your head screaming "FUCKING SMILE BITCH!"
On the plus side people like seeing women smile because it makes the surrounding feel more positive. It's a mental thing

younger women in general are more open/spontaneous/child-like in some ways/ innocent... etc it makes it easier for them to laugh more and be more open and stuff... they are naturally that way, they smile and laugh more and all
men naturally like that, and women generally like peace and the feeling that everyone/thing is on good terms... and smiles make it feel that way
just guessing though lol
