Peanuts had some brilliant moments in its long life. This is one of them.
It’s one I remember when I am grousing about something outside my control. I can turn my mood around by saying “you stupid darkness!” out loud, then laughing at myself. This one and, in fact, the entire Peanuts series are online, for free, at http://comics.com/peanuts. It’s one of the most amazing but little-known Internet resources there is.
