I was volunteering with Global Volunteers in the mountainous Ipalamwa area of Tanzania. While visiting a home as part of a discussion relating to infant health with a mother, some curious neighbor children paid us a visit. I couldn't resist entertaining them while continuing the discourse. A peek-a-boo game resulted which proved to be universal as they soon caught on; smiling then giggling and laughing. With permission, I photographed the moment and shared it with them, which caused more giggling and laughing.
