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, it's frightful, just frightful. And they embrace the pain regardless of whether they broke it or not. One other thing that is very popular in the mind of the society, surely, is the regular shaving of a girl's legs, it happens a lot! How do they deal with their jungles of leg hair if they have any because to not describe would give a gaping hole in the mandatory pieces of information building up the character. I darn hate it if I don't know them well enough to know whether I should like them or not, now thank you very muchly!
