Happy birthday, little brother! If there’s one thing you should’ve discovered from having an elder sibling like me is that we only get more awesome each year!
On your birthday, I wanted to tell you how amazing and perfect you are, and that I would never want you to change even one single thing about yourself.
But then I remembered how annoying you can be sometimes, so maybe you could just change that?
Seeing as it’s your special day, I’ll let you in on a little secret: I know your true age! Well, with us being as close as we are what else would you expect!
Cousin, you’ve completed yet another trip around the sun and boy is that journey starting to take its toll! You’re really starting to show your age now!
Of course, had you thrown a big party on the actual day and invited me, I would have wished you a happy birthday there and then... But, as you didn’t, I’m wishing you a late happy birthday instead!
