Should there be a reason to laugh?

I looked out the window at the sound of voices, voices of bubbly children. Two of them were frolicking, one biking and the fourth one was what looked like teaching himself how to skateboard. From a distance, I could barely make out what they were laughing about. I wondered if the one with a skateboard lost his balance and fell over. Or if the girl in pink skirt cracked a joke or shared a funny story from her school. Or maybe they were laughing 'cause they were just happy. They were perhaps happy without any reason! 

Do you always need a reason to laugh or to be happy? Well, if you are an adult then you do perhaps need a reason. But if you are a child, you do not really care to justify to others why you are making that ear-splitting spontaneous sound and clutching your stomach as you are swaying left to right! 

One of the beauties of childhood is you can laugh without a reason - you can laugh all you want but nobody stares at you or thinks you could be out of your mind!
