Son, not only are you another year older, but today you also reach a very special milestone in your life.
I have to tell you, I am so incredibly proud of all your achievements so far, and I am so very proud to be your father. You have become a truly great man over the past 18 years.
May your adult years ahead bring you all that you deserve, son. Wishing you a very happy 18th birthday from dad.
Each year that I have you in my life to cherish is another blessing, my dear boy, but your 18th birthday is a particularly special year to celebrate.
May all the happiness in the world come your way as you celebrate your first day of adulthood today. Happy birthday, son, from your ever-adoring mother.
If ever there was a time to tell you how incredibly important you are and just how much you mean to me, it would be today on your 18th birthday. Happy birthday and best wishes to you, my dear son.
