Happy birthday from your better-looking and totally awesome younger sibling!
It can’t have been easy growing up with me, especially as I would get away with anything! Don’t feel bad though, sis, the younger sibling is always the favorite of the family!
It simply doesn’t feel right that I’m not with you in person to celebrate your birthday today, but I promise that we’ll make up for it with a huge celebration the next time we’re together, my best friend!
I’m wishing you an exceptionally wonderful birthday today, my dearest friend!
Words can’t fully express just how deeply you and your friendship have touched my heart. Every day since we met has been better and brighter, and I will be eternally thankful that you came into my life when you did.
Today’s the birthday of someone who’s not only my dear sister but also my best friend, too. That’s why it’s twice as hard that I can’t celebrate there with you.
This birthday is a particularly special one as the birthday girl is turning 21! May this noteworthy occasion of yours be just like you: pretty and perfect.
I hope it’s everything you had dreamed it would be and more, my dear.
My dear son, I always have your best interests at heart but I’m sending my very best and extra special wishes to you on your special day this year. I hope everything you wish for today comes true for you.
