     Growing up is not easy. Sometimes all that is need is someone to rely on.

     For many years, she was Mum. My mother was a career woman and has her own problems to take

care, but when I needed her, she was always there. Her strength came from anywhere. I don't quite know,

somewhere very deep. She was so strong that she would never break down, even while I went to her with

all my little-boy problems and shout at her.

     Her strength made me stronger and gave to me courage to try things other thought were impossible. A

helping hand is always stronger enough to lift you up.
