I have only stolen fruits and flowers and food.
When I was a kid, I came from a bad locality (full of buffaloes and pigs), and there were officers' bungalows separated by a road. Sometimes we used to break in through the fences, early in the morning, and steal the mangoes, plums and berries. One day our group broke in the bungalow of a school friend. I was worried about my reputation if his servant caught me, so I crouched near the hole in the fence ready to escape. Others climbed on trees to pluck fruits and some broke the flower pots for fun. That day, when I boarded the school bus, that guy informed me that thieves had entered his bungalow, his mom was scared, and his dad had informed the police.
There was a fair held at our school, for the unprivileged. Poor kids from the area were invited to play games (like tail the donkey, throw a ring), and they were given goodies for free. We were supposed to conduct the games, and we were given the gifts to distribute among the poor kids (these christian missionaries wanted to teach us the joy of giving). But we decided to share them among ourselves, after given the poor kids a pack of biscuit each. That day I went home with my bag full of expensive food (which I claimed to have won as prize).
But as a matter of principle, I never stole money, and always returned any unattended money I found.
