Today is your special day so I won’t make it all about me, but as you turn another year older I can’t help but be reminded of the fact that I’m even older than that! Thanks a lot!
Birthday gifts are overrated I think, sis, so starting from now I think we should just exchange sweet birthday wishes instead! Happy birthday, my dear!
We may have argued at times growing up, sis, but I wouldn’t have changed a thing about our childhood! I’m wishing you the happiest birthday possible today!
You were such a bratty little sister, always trying to take my things and tag along everywhere I went. Things had to be done your way or you would throw a tantrum.
Despite this, I want you to know that I love you to bits.
I was going to make a joke about how you’re getting older, but that immediately backfires as I’m always going to be older than you! At least we can make fun of each other as we grow old together!
Over the years you have driven me up the wall and tried my patience time and time again, but really I have you to thank for that as it’s partly down to you that I’m such a calm, patient, and zen person nowadays!
