Wait, I’m an adult now. When did that happen?

You’re walking down the street or driving your car, or going back to work from a cigarette break when suddenly it hits you: you’re an adult now. When did that happen? When did you grow old, when did you leave behind your younger, naive and innocent self? You’re supposed to be a grown up now, but suddenly you don’t feel like one. Suddenly you feel like you’re not supposed to be here, like the world played a game on you, you pressed auto-pilot and it brought you here, without your consent and all you can do now is play along.
