18th Birthday Messages: Sayings, Quotes, and Wishes

_These 18th birthday wishes can be used for a variety of ways to wish someone a happy 18th birthday including in a card on Facebook, or in an sms text message.  Your 18 year old birthday boy or girl is turning into an adult.  Use the following at your risk to welcome someone into adulthood.

  1. Now that you are 18 and you can legally vote, I suggest you vote for your own party.
  2. Now that you’re 18 the government will treat you like an adult, even if your parents still want to treat you like a kid.  Congratulations on having legal proof that you are now an adult.
  3. No more toys for you.  You’re an adult now.  Expect to only get boring ‘useful’ presents for your birthdays from now on.  Happy 18th birthday!
  4. Have fun on your birthday, but remember to be careful.  Now you’re old enough to be tried as an adult.
  5. Most people will tell you that they wish they had stopped aging on their 18th birthday.  Have fun making the rest of us jealous today.
  6. You’re old enough to drive, vote, and enlist yourself in the military, but you’ll have to wait to drink alcohol and carry a hand gun.  I guess they don’t want you to try out all the dangerous things at the same time.
  7. 16 is about growing up and becoming independent through driving. 18 is about being responsible and being treated like an adult. And 21 is about being just old enough that you probably won’t start drinking if you haven’t already started.  Remember that you are now responsible for your own actions, but the government still doesn’t trust you with alcohol.
  8. Alice Cooper wrote a song about you, and I think you are just now old enough to listen to it.  Enjoy my recommendation.
  9. It’s scary that they let 16 year olds operate a motor vehicle.  It’s scary that they let you vote at 18, but it’s even scarier when you turn 21.  Then they let you carry a hand gun and drink. It get’s scarier and scarier watching you grow up.
  10. Enjoy your rights of being an adult while you still are reckless and energetic enough to get the most out of your new privileges.
  11. Even though you have this year and next year to be a teenager, you’re done being a child.  Congratulations on becoming an adult.
  12. A lot of people think of teenagers as kids, but you are living proof that teenagers can be adults too.  Happy 8 TEENTH birthday!
  13. They say most people’s physical performance peaks between ages 18 and 25.  Enjoy your physical strength and endurance while it lasts.  Happy 18th birthday!
  14. Even though you’re technically old enough to operate military equipment worth millions, be tried as an adult as a criminal, sign legal documents, and kill yourself with cigarettes, you’ll have to wait a few more years before they’ll let you decide to do these things under the influence of alcohol.  Thank goodness you are only 18.
