Cover art for Blooming 18 lyrics by Ace of Base

The song is saying that 18 is a difficult age. You're officially considered an adult, and everyone expects you to act like one, but you are torn between growing up and/or holding onto your childhood. Also, even though you're an adult and should get to make your own decisions, your parents are still controlling many aspects of your life and you feel conflicted and trapped.
