a new set of tires

I took my car in for an oil change earlier this week and drove out with a new set of tires.  Funny how things like that happen.  I'm not really upset about it, I was beginning to realize that I needed new tires, but it was good to have my opinion reinforced.  I had a similar experience today.  My CPA and I finally finished up my taxes, and, as I had hoped, I'm getting a bit of a refund this year, just about enough to pay for the tires -ah well...
