Growing up is not easy.Sometimes all that is need
is someone to rely on. For many years,she was Mum.
My mother was the career woman and 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.
