Your eighteenth birthday has finally arrived, my dear, and it brings me so much joy to see that you’re taking after your old aunt in so many ways. Not least because you’re beautiful and pretty always!
Do you remember how much we fought? Do you know how much we bickered? Do you have any idea of how much we yelled at each other growing up? Can you give me a ballpark figure of how many kicks were given under the table? What's the number of objects we eternally borrowed from each other?
Now multiply all of this and you might get close to how much I love you! Happy birthday, little brother!
When people ask me if I have a brother, I tell them I have someone more than that. What I have is a friend from the same parents. Happy birthday, little bro!
It was boring being an only child, but everything changed the day you were born. I gained a playmate, a friend and someone to take the blame when I misbehaved. That was, of course, until you learned how to talk.
Love you, little bro! Have the most wonderful of days!
