My teacher once said: "Adults like books with a sad ending more than books with a happy ending"

You could say this is because adults are more sophisticated, you could say this is because they know in real life it doesn't always ends happy.

I say it is because, if you have accepted your place in this world, if you wanted to survive to this age, if you for whatever reason you want to stay in this world.


You like suffering



This is a pessimistic way to look at things, (most) people don't like suffering, they do like finding small pockets, small spaces, small worlds without it.
