Happy belated birthday to you

Happy belated birthday and I am sorry
That I forgot your most important day
I am sorry that I could not personally
Call you and wish you well my dear
It's the amazing birthday time
A pleasant time to spread the cheer
I am sorry that it happened this time
I promise that I will not repeat it again
Birthday is a special time
I hope you had an amazing day
Once again..Happy belated birthday!
