Some people in the world are just born with a certain special something about them which is simply unexplainable, and you’re one of those people, my dear. Happy birthday!
As you reach what is possibly one of the most important and significant milestones in your life, I want to send my biggest congratulations to you and wish you all the happiness in the world.
Pretty, perfect, and particularly wonderful are just a few words I would use to describe you, my dearest classmate. I’m wishing you a lovely birthday today.
