Celebrating $2.82 a Gallon Gas

I'm not actually celebrating the price of a gallon of gas being so high. I was on empty on a day I had to drive all over, which is pretty much every day. So, I had to stop and fill up. Sometimes I only get $5 or $10 worth because I'm hoping the price will drop. But gas was $2.82, and it had been that for quite some time, so I risked getting the full tank.

Next day...$2.98! A .17 jump!

What does it say about me that buying gasoline feels like playing the stock market?
