in your selfies you do a lot of smug-ish faces, but never a real smile... don't you think that could look / feel better?
I uh... actually can't do a full smile due to the placement of my teeth (I think). If I try, one side of my mouth goes up significantly higher than the other, hence the smug look. It's not something I can help, but I don't mind it. It suits me I think.
