Jessica making friends

This morning when I dropped Jessica off at daycare she was sitting on the floor next to another little girl (Amber) they were sitting shoulder to shoulder. Jessica raised her arm and put her hand on Amber's shoulder just like best friends would... They then both made eye contact and smiled. That just melted my heart... I don't know if it really was a form of communication or friendship or if it was just my imagination. I do know Jessica LOVES people.
