A little boy invited his mother to attend his elementary school’s first
teacher-parent conference.To the little boy s dismay,she said she would go.
This would be the first time that his classmates and teacher met his mother and
he was embarrassed by her appearance.Although she was a beautiful woman,there
was a severe 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
conference,the people were impressed by the kindness and natural beauty of his
mother despite the scar,but the little boy was still embarrassed and hid
himself from everyone.He did,however,get within earshot of a conversation
between his mother and his teacher,and heard them speaking.
"How did
you get the scar on your face?" the teacher asked.
The mother replied,
"When my son was a baby,he was in a room that caught on fire .Everyone was too
afraid to go in because the fire was out of control,so I went in.As I was
running toward his crib ,I saw a beam coming down and I placed myself over him
trying to protect him.I was knocked unconscious but fortunately,a fireman came
in and saved both of us." She touched the burned side of her face."This scar
will be permanent 8,but to this day,I have never regretted doing what I did."
At this point,the little boy came out running towards his mother with
tears in his eyes.He hugged her and felt an overwhelming sense of the sacrifice
that his mother had made for him.He held her hand tightly for the rest of the
day.
