I had an amazing night's sleep, and this morning I had the most vivid, creative, powerful dreams I've had in a long time. Full of ghosts and characters and imagination, hidden doors and secret rooms. I loved it. As I started to wake but found myself in that twilight in between slumber and waking, I had the profoundly good manners to tell all the people and animals I had gathered in one room, "I had a great time. Thank you, this was so much fun."
Manners, even in dreams, count for something. Learn it.
