If I was a space alien,

sent here to watch society and come up with three things that are so outside the reign of what I am used to but what humans consider "normal" I would choose:

1. Everyone needs to look the same. Smaller aspect of the larger problem of the human need to "fit in."
 Everywhere, on magazines, on television, through reinforcement of their parents and friends, they are told and pushed and prodded to look the same. When one finds a dress, the other wants a similar one. When one sees a haircut, the other one wants the haircut. They find this acceptable. Lack of identity, visually or otherwise.

2. Murder. There is nothing to be gained by taking another one's life. No spiritual advancement, no knowledge, only material possessions, which mean nothing.

3.Religion. They gather in groups and praise named invisibilities. Then they separate themselves from others who do not praise the same named invisibilities. It matters not to them that they are both invisible, the name is what they focus on. Humans seem to focus always on the shell, never the essence.
