Cuteness on the playground

Today while I was in DS2's room at daycare (for lunch nursing), DS1's class was out on the playground. One of DS1's friends saw me and DS2 through the window and started shouting for DS1. When he didn't come, the friend went and got him and brought him to the window, holding his hand. It was so cute! Then both big boys were waving & saying "hi" & knocking on the window. The friend started making faces to get DS2 to laugh, and DS1 started copying him. I've never seen DS1 stick his fingers on his cheeks like that to make a face before. He would look over at the other boy and then do what he was doing. That was cute, too.
