I may not able to tell you

I may not be able to spend the whole day
And I may not be there to talk
But I know that you stay in my heart
That pretty spark on your eyes
And that wisdom being so wise
At times, you do charm with your ways
Your smile leaves an impact for days
Bless to have a cute niece like you
Coz you are pretty one in few
Happy birthday to you
God bless you!
