Dear _____________ (first name of the receiver)
Hi! Hope this letter finds you and everyone at home doing good and going great guns.
So your birthday is here. I am sure you must have lots planned for it – big rocking dances party or something. Did you know “growing old is mandatory, growing up is optional”! And I feel this holds true for you. Each time I meet you I see a child somewhere in you always alive and full of life. Need to learn so much from you.
I pray to God for a long, healthy and rocking life for you. May He shower all His grace on you and your family.
Enjoy yourself on your birthday and every day of the year too.
Take care.
Love
(Name of the sender)
