You’ve got half a century of accumulated knowledge and wisdom! That would be awesome… if you could remember any of it.

A bitter truth! Everyone grows old but not everyone becomes wise and you are one of them. Don’t be sad and enjoy your birthday.

Congratulations! Your belly is no flatter. What an achievement in the 18 years. Happy celebrations!

Be careful my friend! Now you are not legally allowed to cause any trouble because now 911 can be called. Happy birthday, sweetheart!

Hurry up! Find yourself another place to live. Congratulations on entering into adulthood life.

Now you are old enough not to be wished in dollars and cents. So wish you a simple happy 18th birthday.

Congratulations! Finally, you have grown from a small guy in a diaper to a diaper-free guy. Happy birthday!

I think I deserve an Oscar for remembering your birthday and wishing you on time. Happy birthday, dear!
