Toddlers and joy

We attend a large group exercise class at the local Y. As we leave, we walk past a large window into the toddler room.  I make a point of looking at the little kids at play.  Many philosophers have counseled attending to one's surroundings and concentrating on the miracle of it all.   These little kids are way ahead at doing that.  I can see them look at a chair, a toy, a companion with amazement.  How did it, he, she, they get like that?  What are they doing? Can I do that?

I feel a joy rise in me, seeing the way they walk, cooperate, oppose, ignore, worship - all in less than a minute.
