It's really fun watching kids this age because they don't tend to interact very much; instead they do their own thing and watch the other kids. If another kid is doing something interesting, then it's time to imitate.
Desert Boy couldn't resist putting one of the orange cones on his head and walking around with it. I'm not sure what made him do it, but he thought it was fun.
The cone didn't fit quite right, so he had to hold on to it as he walked. It took some concentration.
