I love to patrol yard sales, so I get most of my books used... from my neighbors, for on average about $.25 USD apiece.
I used to have a great sense of direction until I met my wife. She also has a great sense of direction, but with the added need to find the "shortest" or "most-stoplight-free" route. Constantly refining these routes, she also constantly changes how she wants to get places. Being a good doobie, the most frequent driver, and the desirer of positive attention, I learned early on to go whichever way my beloved wanted to go.
Now, years later, my ability to derive my own directions has completely atrophied. I miss landmarks, road signs, turns, etc. I am a hazard to myself and others! When backing out of the driveway, I simply ask, "which way this time, honey?"
Ask for directions? Don't do it! That's like asking for help with your push-ups and sit-ups. All you end up with is flab.
