Sincerity

I'm going to write about something I heard today. Someone said, (I can't remember the exact quote so I'm just giving you the basics)"Once you learn how to fake sincerity, the rest comes easy." It made me think a bit; do people actually try to master being sincere? Are we living our lives around people who are disconnected with themselves so much that they need to master faking sincerity to feel as if they have a one up on others? I do know someone who is so good at making you feel good, as if they care about you, when in actuality they are just telling you that just so you won't get upset. It's obvious that they have other interests but just keep you around because you are actually a really good person to them, but instead of returning the favor you are just on the back burner. The sneaky part of it all is that, when they're near you they can make you feel like the most important person in the world. Now how fucked up is that?
It's pretty bad, but I'm starting to get the notion that it's just the way life is. Fuck it.
