I picked Denton up from YMCA day camp this afternoon (pickups by me are a Friday-only thing) and he exchanged friendly physical contact (hugs, fist bumps) with no fewer than three significantly older kids on his way out the door. In at least one case, the other kid initiated contact, so I don't think it was just Denton.
I find it surprising, in that I remember fairly little cross-age-group contact in my own childhood. I can imagine that it's either a cultural difference (time or location), an individual effect (I was less boisterous and less receptive at age six) or a retrospective effect (my memories of being six are overlaid with my memories of being older than six). Presumably some of each, but now I'm curious about it. (I also don't remember anyone in my age group having much contact with unrelated kids much younger than them, but again, I was probably oblivious.)
How does this fit with other people's experience? Did male kindergarteners hug others all the time in the 1980's? Do they in other places now?
Incidentally, while I recognized one kid as Denton's 'book buddy' from school, he was unable to furnish names and details about any of them. Then again, he was unable to furnish me with details about what they gave him for lunch or breakfast.
