How can Guilt enslave us?

When I was in 3rd grade, I remember my father went to somewhere for a business trip, and he bought a crystal ball for me as a gift. I really like that crystal ball. That day, I was playing with it, holding it in my small hands, flipping it over again and again to let the paper flakes float in the ball. However, the size of the crystal ball is a little bigger than my hands, so my hands just slipped a little bit. The ball fell down to the ground and broke into pieces. The ball is a gift from my father and I just got it for about 3 days and I just broke it. I cried not only because I was scared, but also because I was so guilty! My mother helped me cleaned the pieces and I said sorry again and again to my father. I remember, for the whole week, I was so guilty that I can't look at my father's eyes.
