At the beginning of the week, the road you're driving on abruptly transitions from smooth pavement to jolting cobblestones. And you'll be aware of (and wary of) other cars more than ever before. On Tuesday and Wednesday, you'll see exit signs but will have no clue which off-ramp to take. By Thursday, you'll be resigned to the idea of getting lost, and you'll opt for an exit that takes you to a serene and comfortable place. A field of corn, perhaps? Your adventures this week are adventures of the imagination, and this weekend you might not feel like leaving the house much at all.
