... i will start, some are pretty obvious ones. - when you buy something, and the change is 10c, you don't know whether or not to wait for it. - when you're walking, and the person walking towards you moves to the right, and you to the left like ants. - when you say your peace and greetings to someone, only to realise you have to walk the same way. - when you stop at a red light, and look to the car to your left, and they're already looking at you. - while watching sports with your folks and they get happy over something that's an instant replay. - the hug/handshake/fistbump confusion that is caused every time you're leaving. - when you hear a mate tell a joke that you just told him, and he doesn't credit you for it. - when a mate claims a story you told him was his personal life, when it happened to you. i know there's plenty more, can't think right now.
