There are few things as comforting as being safe in the knowledge that a true, sister-like friend is only a phone call away. Happy birthday to you, my dear!
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 might be growing up in age, but we’re yet to see you grow up in maturity! You still have plenty of time for that though, little sis! Happy birthday!
