I walked four miles!
Fear and tremble, ye New Year's Resolution! I shall see thee defeated until thou liest in thine own hot blood, gasping as ye die a slow and terrible death of agonizing fulfillment.
And let me tell you, four miles is agonizing. Especially since I actually chose to do it. I can't even whine while I do it because it's my own fault!
On the other hand, if four miles doesn't burn off those chocolate chip muffins from yesterday, nothing will.
