In the experience of children, the whole world is constructed around what's convenient for adults: Speak when you’re spoken to, you must be this tall to ride this ride and, of course, the school bell rings at 8 a.m. Typical summer camps are no exception. Children are grouped by age, assigned to a counselor, and move around a set of activities in a rotation. Is this because that is the most enriching, stimulating, rewarding experience people can possibly imagine for their kids? Or just because it's the easiest logistically?
