well i most stupid thing was just a few months ago.. i was going out somewhere with some of my mates up north from sydney and naturally need the money. So i went up the atm, input my account, checked my account, inputed the pin no, inputed the amount in my account, got my card from the atm, got my reciept for the atm and went off to the train station... only finding out later (far away later) i left my MONEY in the atm!!!! talk about STUPIDITY!! i just made someone 50 dollars richer. bah!
