Dressed for a party, I get into the car and change my shoes from UGG boots into nice tall open toe wedge heels. The BMW does not catch first time, so I crank it over some more while pumping my foot on the gas pedal. I quickly realise that something must have drained the battery, as the car is cranking slowly and the lights inside are dimming with ever crank. Unsure what has happened, I didn't leave the lights or the stereo on, I try to get the car started, or I may just have to put my UGGs back on and walk to the party!
