Most humans lack perspectives. I.e they are always looking at things only from their own glasses. The moment they see some one that is different from them they dont think that person has his own set of paths that led him to that exact moment. They self-project their own history and then ask "why would he be like that?" or "why woukd he do that?". Because if they were in his shoe they woukdnt do it! That's what they think but they are totally unable to see his shoe size because they lack perspect
