Dandelion Wine by Ray Bradbury.
In one passage, twelve-year-old John is moving away and he asks his friend Doug if the building they pass everyday has always had a colorful, round window. Yes, Doug replies. How could I have passed it every day and never noticed, John laments. He begins to wonder what other beautiful things his young eyes have overlooked or never noticed. In some ways the adult Bradbury is ruminating on his own past and grabbing the reader by the lapels..."Remember," he seems to say.
John then tells Doug:
"Some nights it happens to me in my own house; scares heck out of me. I got to go in my folks' room and look at their faces while they sleep, to be sure!"
Finally, he implores Doug (as Bradbury most assuredly is imploring us), "Remember me...oh, please remember me!"
