When I was six or so I first learned the story of Robin Hood, only I misunderstood one vital point: I thought that King Richard had gone off not on the Crusades, but rather an actual cruise. I didn't understand why everyone thought Prince John was such a bad man because I'd be angry, too if my brother went off on holiday and left me home alone!
