Happy birthday to the most mature 18 year old I know!
You are wise beyond your years, but don’t go around thinking you know everything. Living is constantly learning and your age is but the number of the lesson.
So, enjoy life like a good book, only stop when you get to the end.
Dear cousin, today we get to celebrate yet another fantastic year of your life.
I hope you have a day that is as sensational as you are, and I wish that with this birthday life continues to bring you good health, good fortune and all the happiness possible.
