The day you understood that everyone is imperfect, you became a teenager. The day you forgive them is the day you will be an adult.

You can grow older but please please please please please please please never get old.

I hope you’ll keep an open heart and open spirit as you gain life experience.

My only goal today is to make sure you have nothing to worry about. Save your worrying for tomorrow.

These are special years now, where you are neither very, very young nor very, very old. But for you, I hope that they are very, very happy.

Your age only matters to the police and insurance companies. To people who love you, you will always be ageless.

Today, let’s not say 18 years old and instead say 18 years young.

Happy, happy birthday for a dear, dear friend!

Since it’s your 18th birthday, I’m wishing 18 times for your continued success!

Thank you for all the joy you’ve brought us through the years. You have a special heart.

Now that you’re 18, you need to be careful—your parents can legally throw you out! Happy 18th!

Now that you’re 18, you need to be careful about the mischief you cause or else. . . we can sue you!

On your 18th birthday, we wish you a fantastic party and an even better year!

Welcome to manhood. It’s time to leave childish things behind (even video games). Happy 18th!

We’ve known you were wonderful for each of the past 18 years. Hope you have a great party tonight!

Great! Now I can arrest you legally ;)

Welcome to the adulthood club, where we only have one rule: No rules! Happy 18th birthday, dear!

Now that the most carefree days of your life are behind you, get ready for the burden of adult life.

Another year older, and you just keep getting more amazing! I can’t wait to see what this year brings for you.
