This just shows us how children express simple joy in laughter itself and not hung up on the object of their amusement. If one is open to joy and allowing in the feelings of elation and happiness that is possible, we can be moved to laughter any time we like.
Enjoy this charming video of a father reveling in his young sons crazy laughter at something so very simple. Enjoy!
