You have just learned the lesson that so many others need to learn - getting active interest from others has almost nothing to do with how you look. It's all about how approachable and interactive you are.

If you engage in small talk and look interested in others, they will be interested in you. If you are aloof, shy, quiet, or always appear self-involved or busy, they will not approach you. The exceptions to this will be people with really shitty social skills or nothing at all to lose.

Make an effort to be more social.
