Protege

My brother and I are vastly unalike.
He knows how to use a band saw.
He can judge whether or not an item is level by using his eyes.
I need a level.
I like to recycle.
How do we get along?
Besides the fact that the law states we have to, he says fun things like: "I'd rather have a roll of duct tape in the house than a smoke detector."
All of the pictures we hang are straight.
