I am sending a big hug your way on your birthday, bro!
You are so important to me and such a big part of my life. I want you to know that you’re more like family to me and I don’t know where I’d be without you. You mean the world to me, man!
Enjoy your special day today and I can’t wait to celebrate with you!
Since it’s your birthday today, little bro, I’ll let you have the spotlight. After all, it must be annoying having an amazing older sibling who usually gets all the attention!
