Friends?

So, a funny thing happened last week. When I was walking Miss C into her class she pointed to one of her classmates and said her name "Nomi" (its Naomie but you know). Ok, so that's pretty cool but what happened after is even better.
We had to put up our stuff in one room then move to another because we were there with the early group. They congregate in one room until there are enough kids to require more than 2 teachers. Anyway, so we walk into the other room and Miss C walks over to this other little girl and they touch hands. Are you still with me?
When I went back to pick her up, one of Miss C's teachers told me that Miss C and "Nomi "are buddies. They apparently greet each other with hand touches and hugs and play together! Isn't that just the coolest. "Nomi" is a couple of months older than Miss C but they have been classmates since we got into the day care.
Needless to say, i am a little surprised. I didn't think kids really played together at this age. I think its cool though to know that Miss C looks for her little friend every day and when she sees her, she is set!
What do you all think?
