Well, when I -- looking at the question, kind of as I answered it earlier, we got to stay forward looking. Can we pull costs out quick? Well, absolutely, we can. I mean, our locomotives, when you think about that, that's a daily cost. You put it down tomorrow, you stop paying for it tomorrow. I mean these are assets that have been around a long time. And we haven't bought a new locomotive in many years, even though we have a rebuild program other than depreciation, the heaviest cost of a locomotive is which you use every day on them. So, I mean, that is one example of costs that we can handle. And on our T&E side, it's important that we continue to build our T&E workforce where we need it to be. And if we get into a position where things get deeper or things look differently, that attrition, as you mentioned, Chris, it is a heavy attrition rate, and we're able to use that as just a natural way to control our numbers. And by pausing classes, if we get to that, those numbers will take care of themselves. But we -- on the T&E side, and I'm going to keep emphasizing that, we -- it's a very important position like any other in the company, but it takes four months to six months to make a train conductor. And if we get softening market and we come out of this, we are going to be prepared to handle all the traffic that comes back at us and that's a commitment that we're making, and we're going to continue to follow through on that. So all those other levers, there's a lot we can pull in this industry. We want to make sure that we're prepared to come out of any softening if we get to that point.
