When we lived in a tiny flat in London Jimmy and I once had a humdinger of an argument about the quantity of books that we were housing. Me: get rid of some. Him: Not on your nelly.
It ended with him storming out of the room, slamming the door as he left. Milliseconds later the makeshift shelf laden with books, above said door, fell on top of him and I laughed A LOT.
Although I reckon I definitely won that argument, I am very cautious about ever bringing up the subject of "too many books" .
Jimmy's shelf construction skills haven't come on very far but at least his storage solutions are relatively pleasing to the eye.
