Charles M. Schulz said this quote

Rats! There goes the bell... oh, how I hate lunch hours! I always have to eat alone because nobody likes me... Peanut butter again... I wish that little red haired girl would come over, and sit with me. Wouldn’t it be great if she’d walk over here, and say, “May I eat lunch with you, Charlie Brown?” I’d give anything to talk with her... she’d never like me, though... I’m so blah and so stupid... she’d never like me... I wonder what would happen if I went over and tried to talk to her! Everyone would probably laugh... she’d probably be insulted someone as blah as I am tried to talk to her. I hate lunch hour... all it does is make me lonely... during class it doesn’t matter... I can’t even eat... Nothing tastes good... Rats! Nobody is ever going to like me... Lunch hour is the loneliest hour of the day!
