Two weirdos
It is a tale as old as time itself, weird people just attract other weird people, it is what it is. Do not ask us why such an attraction occurs, it just does and you have to accept it and move on. Weird people are everywhere and need to find each other in order to not feel so alone.
But then we have to ask ourselves, just what does it mean to be weird and what does it mean to be normal? Anyone can be considered normal, but once you get to know them well, all of a sudden the mask is lifted and the freak comes out to show its true face.
