Friends

Friends are just people that see you as an individual living with a low standinging in the society. They approach you to benefit themselves to gain reputation. Being in a "pack" will never benefit any one individual no matter what. Humans find it unnecessary to do things out of the ordinary that will not benefit themselves.
They only want people to see them as what they want to be viewed as, but to me they're all trash. I see no need in having friends, much less acquaintances that intrude your quiet, daily life.
They create the need for those they have strong requirement to have a high social stranding. They want to live a fulfilling life surrounded by others. They will be satisfied when you don't bring them down.
