     A little boy invited his mother to attend his school's first teacher-parent meeting. When she said she

would go, he was disappointed as he had always been ashamed of his mother's scar that covered nearly

the entire right side of her face. The boy never wanted to talk about why or how she got the scar.

     At the meeting, the people were impressed by the kindness and natural beauty of his mother in spite

of the scar, but the little boy was still embarrassed and hid himself from everyone. He did, however,

overhear a conversation between his mother and his teacher.

     The teacher asked carefully, "How did you get the scar on your face?" The mother replied, "When my

son was a baby, he was in a room that caught fire. Everyone was too afraid to go in because the fire was

out of control, but I went in. As I was running toward his bed, I saw a long piece of wood coming down

and I placed myself over him trying to protect him. I was knocked senseless but fortunately, a fireman

came in and saved both of us." She touched the burned side of her face. "This scar will be lasting, but to

this day, I have never regretted what I did." At this point, the little boy came out running toward his

mother with tears of regret in his eyes.
