There were often times when i wondered how it would be like when most of my siblings would be grown ups, or would earn their own living or would drive their own cars. Likewise there were also times when i stopped myself from imagining how it would be like when my parents would grow old and age, and would lose their health bit by bit, taking turn one after another.
I always believe one can never be prepared for ailing parents. I believe we wouldn't even have time to feel when the time comes. We do what we have to do.
We feel later.
