One funny message for an 18th birthday is: "Happy 18th birthday! You?re an adult now, which means you can do everything legally you've been doing illegally since you were a kid." The message pokes fun at the milestone of reaching legal age.
Another funny 18th birthday message is: "Happy 18th birthday. You?re going to fit right in with this crazy world of adults. Welcome and enjoy yourself? but not too much." This message emphasizes the leap into adulthood that takes place when someone turns 18, and humorously warns them about having too much fun with their new adult privileges.
18th birthdays are significant in many countries because they signify the year when teenagers become legal adults, and they are granted many privileges such as driving, voting and enlisting in the army. Birthday wishes for 18-year-olds commonly highlight these new liberties in a young person's life, as well as acknowledge the rite of passage from youth to adulthood. Wishes can be funny, serious or heartfelt in nature, but should avoid clich?s. People can make the wishes more practical or inspirational by adding tips and advice to them, such as messages about working hard, exploring new opportunities, embracing change and capitalizing on life.
