Children resist the urge to respond with expected responses and are encouraged instead to produce unique answers. Don't bite the hand of someone who doesn't wash after using the toilet. If at first you don't succeed hire someone to do it for you. You can lead a horse to water but you can't lead water to a horse. You've seen it a million times.
Football players do their own special strut after scoring.
Little children gesture excitedly on Christmas morning as they unwrap that special toy. Start by just paying attention to how other people celebrate. Pay attention to how you react to good news. Create your own individual celebration strut and have. Feel free to add sounds and movement.
