One of the highlights from Kung Fu Panda 2 is the pondering from Po, the panda, on the question "Who am I?"
I think all of us, at one point or another, may have a similar question popped up in our head. We often let some past experiences define who we are.
According to Kung Fu Panda 2, we cannot go back and change the past regardless of how much we may want to. Of course, the past may leave scars. But scars do fade.
