Why is it that in books...?

They don't go into trivial details such as farting and peeing and scratching the nose-I thought it was the trivial details that made it interesting and furthermore I would love to read a detailed report on poo scraping buttock. I wish I could just see it when they dig their finger and pick out a piece of treasure, I'd love ever bit of it because it would come out so realistic! And chores and cleaning out the garage and going to a public restroom and feeling embarrassed because you just plopped and going to bed and stubbing their toe. Stubbing their toe especially, thank you very muchly!
