Why do most people have a deep-seated concern of what people think? I understand most people do but some people resist the urge and do whatever the hell they want. Here's my theory on why we are like this:
It's ingrained in us as humans to be this way so we won't stray too far from the middle. We need to be alike so that we can relate. And relating leads to relations, which leads to procreation. So, we do it for the greater good of the human race.
