I read a short story once about a woman who woke up one morning dead and nobody would let her move on. She kept telling her husband, her kids, her friends, etc., "I'm dead" and they'd say, "Well, let me tell you about the day I'VE had!"
Her husband would say, "Can you pick up the dry cleaning?" She'd say, "I can't....I'm dead, really I'm dead." and he'd reply, "OK, don't forget to make sure the vest is with my blue suit because they forgot it last time."
Her son would say, "You need to take me to the sporting goods store after school 'cause I need new soccer shoes." She'd insist, "I can't, I'm dead" and he'd say, "Oh, and can we stop at McDonald's afterward?"
You get the picture..... For the life of me, I can't remember how it ended but I'm sure she's still picking up the dry cleaning and taking the kids to the mall.
