Your naughty pranks I know

Your naughty pranks that I hide
Your smile seals it all for me
I can see that love in your eyes
All the lessons of being wise
You cannot do without me
I am aware of the same my dear
Whenever you had some apprehension
Or you had some kind of fear
I only know things I do,
Starts with you and ends on you
You are my life and you are special
To me every way my grand daughter
Remain as sweet as you are in life!
