write letter to your father and invite for your birthday.

Dear student,

Here is a sample letter for your reference.

Dear Daddy,

I hope you are doing well.

Since coming to Pune, there has not been a moment where I have not missed you and mom. I desperately want to see you. I know you don't like travelling. But dad, how about we go for an adventure this month?

My birthday is coming and I want to take you to the different corners of this beautiful city. You always said you wanted to visit Lonavala. This is the perfect time. My friends are also hosting a party for me. 

Please come with mom and give me your blessings. Nothing compares to your presence on my special day. 

Yours lovingly,

PQR
