No One Remembers My Birthday

"Hey everyone, come to my birthday party!"
I've been waiting for
This special day
Everyone will come
To my birthday party
What's my present?
Is it a teddy bear?
This will be a happy day
I will be the star
Knock, knock, knock
Knock, knock, knock
Who is at the door?
Are you my friends
With my birthday gifts?
No, I'm not
No, I'm not
I'm a policeman
I have come to return a lost wallet
I've put on a dress
Blew all the balloons
My strawberry cake
Looks so delicious
What's my present?
Are they color-pencils?
This will be a happy day
I will be the star
Knock, knock, knock
Knock, knock, knock
Who is at the door?
Are you my friends
With my birthday cards?
No, I'm not
No, I'm not
I'm the postman
I am here to deliver letters for your mom
"No one remembers my birthday."
"Happy birthday!"
Happy birthday
Happy birthday
We have planned a surprise birthday party
Happy birthday
Happy birthday
Everyone at this party
Loves you very much
"Thank you so much!"
