For a long time, I really resisted thinking of myself as an adult, even once I know I was definitely already well into that stage of my life.
I guess I was reluctant to think of myself as someone who is no longer given a free-pass to be silly, immature, and without any responsibilities whatsoever. But when you reach a certain age, there's really no denying it anymore: you're old, baby.
If you've also accepted you've leveled-up into the "boring adult" stage of life, then I think you're really going to enjoy these quotes!
