I'm nearing 30, and I have adult coloring books, I still watch all of my favorite childhood movies, and you will always see at least one bright color represented in my outfit or on my nails. I don't feel like an adult and I'm not sure I ever will.
My mid-twenties have taught me that "adult" is a relative term. I absolutely do not plan on growing up. I work at a children's museum and regularly peruse the internet for the cutest animal pictures/videos (much to my boyfriend's perplexion). Never forget what it's like to have fun and find the joy in everything! Also, where do you find these adult coloring books?
