I had a phone message this morning from the nice guy who supplies my fuel oil. He said, “I noticed on your last delivery that your X-factor has more than doubled since last year. [The x-factor is an estimate they use to predict when you will be running low on oil and need a delivery.] So the computer is telling us to wait almost an extra month before bringing you oil, and I’m worried that it’s a mistake and you might run out of oil. And I’m also worried that if it isn’t a mistake, your furnace isn’t supplying enough heat for you. So, just give me a call and let me know what’s going on.”
I was joking the other day that the oil guys would be surprised, when they came to deliver, by how little it took to fill the tank. But it didn’t occur to me that they’d be so concerned about it that they’d call to ask about it!
