May this birthday of yours be another fabulous one in a long line of beautiful celebrations and magnificent milestones in your life! A best friend as truly dear as you are to me deserves as many glorious moments in her life as possible.
I’m wishing you a heartfelt happy birthday and sending the most meaningful wishes your way today, brother, to let you know that you truly mean the world to me.
There isn’t another sister out there luckier than I am, since they don’t have you as their brother.
