Remember when you were a small child and how easy it was to make friends. You could go to a play park, to school, or maybe even the grocery store with your parents and just start playing with random children that you had never seen before. When you're young, you have less inhibitions, less self doubt, and less influences about who you should interact with, in general. As we get older, though, we tend to be more guarded. We become more concerned about how people view us and therefore we make less friends and even when we do, it is hard to let people past certain barriers or layers.
