If Weirdness is merely aberrance from the norm; from the average, than everyone is a bit weird, but is mostly normal, and that deviation therefore would also be normal. How do we define it? And if everyone is partly weird, than isn't it...normal, thus making it not so weird, except upon the surface?
Thats exactly it in some ways. People have all sorts of hobbies, habits, attitudes, things enjoy and yes - problems; normal is an incredibly broad category. Which includes everyone in this thread.
