Happy birthday to the most intelligent person in our class.
Your dedication to your schoolwork is so inspirational and I sincerely hope that you achieve everything you are striving for this year, as you deserve it more than anyone I know.
Wishing you a very happy birthday today! It has been such a joy getting to know you, in and out of class, and I’m looking forward to many years of friendship ahead.
I’m glad that we get to share this class together; you always manage to add a touch of brightness to my day. I hope you have an enjoyable birthday today.
