When out and about in the world I love seeing, what I believe to be, teenagers playing with younger siblings or little ones in their care. The other day, I watched one holding onto the hands of a little— both laughing— while the little, very enthusiastically pulling the older, led the way towards their unfolding adventure. Some days later I saw another duo. This time the older was in pursuit of a young one, with the former moving in such a calculated way that the pursued looked convinced, and thrilled, at what, undoubtedly, felt like an all out chase.
