We human always have the tendency to forget the goodness of others, in another words " take someone for granted", especially to our parents.
When they grow older and down with short memory and started to ask a lot of questions we get annoyed easily, but do we still remember when we were little we always ask questions but they patiently answer our questions, why? why? why? why? why? they will try their very best to come out with the answers.
This is the time to reflect and start to show our appreciation to our parents.
