Happy birthday to a truly fantastic teacher who’s a personal favourite of mine!
I can’t fully express how appreciative I am for what you’ve contributed to my learning and all the knowledge you have imparted onto me. I really am eternally grateful to you for everything!
No matter how old we grow or how far apart from one another we may be, you will always be the most special sister to me. Happy birthday, dearest sister.
I would tell you not to grow up too quickly and simply cherish the years, but you seem to be doing a pretty good job of that all by yourself, my dear sister!
I’m wishing you a very happy birthday and sending a big kiss!
