I was walking in the streets of Harderwijk, Netherlands, on a hot Summer afternoon when I noticed this child sitting on a slide alone in a playground. It seemed as if he was making a decision whether to go for the thrill of slipping on the slide or to hold on to the joy of this ride. This is metaphoric to how fast childhood slips through our fingers and leaves us with only a memory of all the joys and innocence of being young and free: as fast as slipping on a slide.
