We took the kids to a big, indoor play area and Ryan, as he often does, wore himself out and then wandered into the toddler area to rest. I think he prefers being around the smaller, less-aggressive kids in general, but especially so when he's tired.
Ryan is a well-above-average sized 10-year old (girth-wise), so when he goes to the toddler area he looks like one of those huge, oversized teddy bears you might see in the front of a toy store, with a lot of small children running and crawling around him.
My wife went to check on Ryan, the boy-giant sitting amongst the babies and toddlers, and a small boy was standing next to him, hugging Ryan, and giggling.
"How cute," she thought.
She got herself situated, found a chair and sat down and then looked around for Ryan again.
He was in the same spot with the same boy, who was latched on, smiling, and not letting go.
After a bit longer, my wife approached them.
"Who is your friend?," my wife asked.
"This kid really likes me," said Ryan.
Eventually, the little boy let go and went back to playing, but it's funny to that while he was running around and playing he saw Ryan and was completely overcome with the desire to hug.
...and now I'm wondering if the boy just though Ryan was part of the play equipment.
