Sweet, sweet little scene

Yaya and Peter have began to enjoy each other lately. Yesterday, the big kids were allowed to watch some movie at 5pm in school. It is not very common, therefore all the kids were very quiet and attentive when Peter and I went into the classroom. Yaya, likewise, didn't even notice us. Then when Peter was put down on the floor, he noticed that Yaya was sitting in the back row. He went up and "said" something. Yaya turned around and found his arms wide open. She responed him with a big, warm hug and also a kiss on his cheek. Peter seemed to be so happy about it and he went towards me, but returned to Yaya right away. Yaya turned around and they hugged and giggled together. The same thing happened another time. It made me feel so happy.
