Wait, lemme get this straight. To the Jacobses and back is 4 miles, so that must be 2 miles one way. Run there, that’s 2. Go back for your wallet, 2 more. Back to the lemonade stand, 2 more, now up to 6. After that it gets a little fuzzy. Wouldn’t it just be another 2 miles back home to use the john, for a total of 8? Where does the 12 come from?
