So, by now, you're all too familiar with the straight-line route from point A to point B in this new city you recently settled down in. You confidently begin your drive back to point A, with the GPS navigator plugged in as a (safety!) backup.
Oh look, here's a road the GPS beckons you take. You know that the one you're currently on will get you to your destination in a few minutes. But hey, it's a lovely Fall afternoon and you decide to be adventurous. You place your trust in the GPS even though it has played tricksy, deceptive Gollum to you on several occasions.
Lo and behold! The right turn is now taking you on a road through woods - dark and deep. This is not where you want to be. Darn it, GPS!
Some distance later you find a spot to turn around. At this point your GPS turns into Sirens to your Ulysses, luring you, "turn right on ....place, turn right on ...road, turn right on ...street." But, you're Ulysses, of course! You steel yourself, ignore the shrill beckoning and drive on. Now, you come up on unfamiliar sights when you thought you were retracing the path out of the woods. Ok, now you might be getting deeper in the middle of nowhere. Fine, come hither Sirens, lead me out. You turn back to the GPS and slowly but surely make your way back to A. All you wanted was to get to A to be able to get to your bed for a siesta. But now, you have a writing emergency. Goodbye, Siesta!
