From one twin to another, I want to wish you a very happy birthday!
Speaking from the heart, though, you are so much more than just my twin. You’re a brother and a best friend, too! I know that I can count on you for anything!
I’m wishing a very happy birthday to you today, bro!
I’ve spent so many years laughing at you and I’m sure that I’ll spend many more laughing with you! I’m so lucky to have a funny younger brother like you!
Happy birthday, little brother! You might be jealous of your big sister in many ways, but I’ll always be envious of the fact that you’ll always be younger than me!
