sum types of people:
dreamers - (i know this one, i was married to one) they dream up all these things they are GOING to do but never do, even when you back em up and say "go for it"
users - those who leech off you
Do'ers - yay they're a winner
"holier-than-thour" - you can never do anything right and they are always right, you will always be blamed for everything, even when the other person DID do it
nasty - just stay away from them
