Freaking Tire

So I am on my way to work today, I live 15 miles away, and I hear this funny noise. I am thinking that it is just my hubcaps because they sound a little like the rattle of a plastic shopping bag; but then my car started to veer to the left. At this point I am starting to realize that I probably have a flat tire. I pull over, turn on my flashers and hop out. Sure enough, the tire is flat. Wonderful. Since I was only halfway to work, and in a no service zone, I was a little perplexed as to what I was going to do at this point. I turned the car around thinking maybe I could drive it a ways, but to no avail. Luckily at this point I discovered that I had one bar on my cell phone. Praise the Lord! I called my sister and she came and saved me. I still had to go to work though, so that really sucks!
