When he was like two or three years old, we were out play in a playground somewhere. And i think his parent wasn't hovering over, and i said, o hey, that kid fell down. Can you go give him a hug and tell him it's ok and try to help him? He just ran over there and put his arm around this kid and like patted him on the back. Ever since then, since the age of three or four, d now he just does it automatically. Any time he sees any one get hurt or sad anywhere, he immediately, like a rush, is over and puts his arm around them.
