Many congratulations to you on this very special birthday of yours!
Of course, we all know that the big birthdays are every decade or so, but the truth is that when you get to your age every year is special and cause for celebration!
Someone as special as you deserves a fabulous day full of celebration!
You are the warmest, kindest, most considerate person there is, and I feel very blessed to be able to celebrate this wonderful occasion with you. Happy birthday to you today.
Each year of your life is a blessing and every birthday of yours is special, my dear, but this one even more so. Happy 18th birthday, my beautiful daughter.
