By the roadside I found a bottle with a Jinni inside, picked up the bottle took it home, next day the Jinni knocked and said: 'let me out, I've been eating beans and need fresh air.' Looked ill he did, face green and sweaty, so I uncorked the bottle, only slightly to let bad air out, but the stink was so awful that I fell back and lost the cork. Jinni was out and laughing.
'I'll grant you three wishes' he said, I know you're short of money.' 'No, I don't want your wishes, they only come true, and then what do I do?' Instantly knew I had said the right thing, without human greed the Jinni can't function, defeated it slinked back into the bottle, but I'm not a teacher, put the bottle, near a bus-stop, for someone else find it and learn a lesson
