What makes us smile? What is it that causes us to laugh? Is our mind tickled by an image? A thought? An entity? Does a person, a friend, a family member, evoke such irrepressible joy that can't be contained by the boundaries of our lips? Does a memory trigger a roar that echoes within our very being and becomes so loud we must express it outside our material bodies? Does an action really speak louder than words, and in so doing, produce a part of us that we so desperately wish to hold on to?
