I literally just thought of this and am submitting it via iPhone so pardon any grammatical errors.

I'm sitting in a waiting room browsing reddit and naturally a lot of the submissions make me laugh, but usually when in public I just smirk and smile. There is a cute girl sitting accross from me and I realized that naturally smiling from reading funny things is a good way to get me to put on a good face. I don't know if this could help build some sort of attraction but I don't think I could hurt. It could also be a good conversation opener by sharing what your looking at.
