Selfless or Selfish?

Are we selfless or selfish? I think that most people put others before themselves, but we are all a little bit selfish. No one is perfect and everyone has to be a little bit selfish, otherwise we would be perfect. Little kids are selfish all the time, they don't understand until there older that the world doesn't revolve around them. Even adults are selfish. They might not want to share money with someone who really needs it, even if that person would pay it back. I think that almost everyone puts others before themselves, but we aren't perfect.
