I know that I am the one

I know I am the one; I have pampered you a lot
People come to me and crib about this
I gave you permission for everything
I gave you so many reasons to chill
If you are the best niece, I have
Then be thankful to me as well
I am your best aunt my dear,
Together we do spread the cheer
Many smiles and wishing you a good time
Happiest birthday to you
May you stay blessed and through!
