Dead Battery

I am a city girl, born and bred, which means I am pretty dependent on electricity. So I'm driving down Delmar on my way to pick up a friend at the airport when I pull into the Walgreen's parking lot to reply to her text. "On my way" I sent. Two seconds to text it, but when I went to start the car back up, my battery was dead. No juice, no lights, no radio - nothing. I knew the battery was getting low. I noticed that the car didn't start well when I went to the grocery store on Monday (guess the car didn't like sitting in the garage for 6 weeks, even though Bruce drove it to work 3 times while I was gone - either that or the fact that the battery is 7 years old). I have Triple A, but my service doesn't cover picking up friends at the airport. And my knight-in-shining-armor who usually bails me out of these situations was currently flying over the Atlanta airport. So I called my friend back and told her to take MetroLink downtown. Needless to say, she was a little disgruntled, but she was going to be even more stressed in a few moments when the train hit the MetroLink stop after the airport and hordes of Cardinals fans would cram in on their way downtown to the baseball stadium. Me, I was sitting in the lot worrying about leaving the car in the Walgreens lot with all the windows rolled down (power windows - I couldn't get them back up), when I realized that no one would be able to steal the car, since you can't "hot-wire" a car with a dead battery. So I walked home, got a beer out of the refrigerator, and used the cold bottle to cool the sunburn I got while walking home in the 95 degree sunshine (like usual, St Louis skipped right over spring and went straight into summer). Long story short, Bruce got home, got the car started, and I drove it straight to the Firestone complete auto care lot. Do I know how to handle an emergency situation, or what????
