Young Love, akin to Pac Man

Recently, while at the park, my son found a new playmate.
They meet.

They Chase each other.

They Play.

Neither of them could talk very well to each other, but the little girl introduced herself by bringing my son a leaf. I told him to pick a little white flower and take it to her. He did. They started playing immediately. Wouldn't it be nice if adults could communicate that easily?
