If you ever start feeling like you have the goofiest craziest most dysfunctional family in the world all you have to do is go to a state fair. Because five minutes at the fair you'll be going 'you know we're alright. We are dang near royalty.'
I think the most important foundation about any relationship is just being honest. You've got to. My wife and I are honest to a fault with each other and we're best friends on top of it so we're very fortunate.
