Short story before I hit the tunnel:
He was abused. A poor boy with nothing to his name but a rotten banana and the clothes he wore. His flatmates had asked him—well, flatmates only because they allowed him to stay in their home indefinitely—but in any case, his flatmates asked him constantly why he never did anything with that banana. It’d been healthy once, flush and firm, ripe and ready. Yes. It had been healthy once. He could have made good use of it before it turned foul and mushy. Put it in a blender, made a smoothie. Stuck it in the oven, baked a pie. Instead he let it flop around in its rotten state. One flatmate suggested he freeze it and throw it at a bum, although this didn’t make much sense to the poor boy. His other flatmates had laughed at the proposal.
