'Happy Mother's Day' means more
Than have a happy day.
Within those words lie lots of things
We never get to say.
It means I love you first of all,
Then thanks for all you do.
It means you mean a lot to me,
And that I honour you.

But most of all, I guess it means
That I am thinking of
Your happiness on this, your day,
With pleasure and with love.

Shashidhar Kumar
