The old lady..

There is an old lady selling fruits at her small stall located in the same row as my mum's shop.. One day, long long ago.. i and mum passed by the fruit stall and saw the old lady..she is about 70 something if i have not mistaken.. mum told me the story of this old lady.. this old lady has 2 sons whom are both mentally unstable..she earns her living by just selling fruits..i mean, she need to earn for living for her sons as well.. at times, i really feel sad for her..she is already so old but she still need to take care of her sons..sometimes i would think wouldn't it be much better if she could get rid of them.. however, i know this is impossible.. i can't 100% understand a mum's thinking..but i do know that no matter how useless is her sons..she still loves them and care for them as long as she could live..
