The 20 y.o. people I live with at Uni are utterly useless at everything. They had no idea what to do when the sink was blocked, and when I undid the trap I discovered one of them had shoved plastic straws down the plughole, as though they would just wash away. They have no idea how to cook anything, it's all frozen food in the oven. Their parents have showed them no survival skills whatsoever (or they willfully refused to learn them).
