I was given this book as a shy kid. I've read it multiple times. It really should be titled, "How To be a Decent Human". Show genuine interest in everyone you come across, and everyone's day ends up much better. I'm still bad at remembering names no matter how many tricks I use, but I'm really good at remembering other people's stories and interests. I also learned that so many people have amazing stories to share, and are just waiting for someone to ask.

If being friendly with people is manipulation then I don't really know what to say. I'm more likely to help someone if they are not being a jerk and vice versa.
