If you're lucky like me your relationship with your brother has resolved itself on the peaceful side of the fence and has stayed there. But if you're someone who's got a family that's all fractured and finding it hard to relate that's a very sad place to be.
Anything that's different from your own realm of experience as a human being whether it's driving a car or a boat or using guns anything that separates you from yourself and leads you more towards this character's existence is a big help.
