Happy birthday to someone who’s getting on a bit now!
I know it might feel like age is against you as the years are really stacking up, but really what’s one more year at your age? By now they must all just blend into one anyway!
Many happy returns to you, I’m wishing you an amazing birthday today.
I hope you know that you are such a happy and delightful girl to be around. Your wonderful personality fills the classroom with joy and spreads so much happiness throughout.
