Have you ever done something or said something that made you stop everything and think, "Wow... I really am an adult now"?
Yeah, same.
Sometimes I really surprise myself with how "mature" I've become (you know, mature meaning "boring" because good god, I've become a supremely boring person). But hey, that's just the level of life I'm on now, I guess.
If you're also feeling your adulthood, I think you're really going to enjoy these quotes.
