Twenty-one is the last of the threshold birthdays — the one with the toast built in. The card's job is to raise a glass and say something worth remembering through the celebrations.
Twenty-six options: toast-ready, parental, and responsibly irresponsible.

Parents: pride plus one knowing wink ('first round's on us', 'text when you're home') hits the right register for a kid who's officially grown.
The hydration/recovery joke is the genre's classic and lands best from friends — pair it with one sincere line so the card outlives the hangover.
A toast with a heart: 'Here's to the years that built this person and the years ahead that get to meet them.' Add one celebration joke and one 'get home safe'.
'Adulthood level 2 unlocked: same responsibilities, better beverages.' Funny-21st formula: celebrate the freedom, wink at tomorrow morning.
