The best
The worst

On the crest of the wave of life,
On the trough of the wave of life,

The moment when no one is with you,
The moment when everyone is with you,

The moment when you need them,
The moment when you don't need them,

They were always with you,

They were your parents.

This is not that good because we can't describe such precious gems of god send to us. :)

Whatever parents do, they do for us to make our lives better.
