I would only say on the call standpoint, I mean, obviously, we've switched to where our variable costs or the majority of our cost base now, probably 70% or more of our costs now are variable in nature. And obviously, we've got a big fixed cost base and we're seeing the loss leverage with the revenue decline there driving some of that. But some of the increase in those overhead costs in the first quarter also comes from the fact that we're on a little bit of a different schedule with respect to our equipment plan. We were taking delivery in the fourth quarter of equipment, taken delivery in the first quarter, which is unusual and that was part of why we had anticipated a sequential increase in those depreciation costs as a percent of revenue. But given all the challenges from a fleet standpoint, that's driving some of our costs. It's also driving some of the maintenance and repair costs, like I mentioned. We're seeing an increase in cost per mile. Some of that is just due to general inflation related to parts and repairs. But some of it, too, just relates to the fact that we're bringing in equipment. We've -- on a different schedule, we've held equipment through '21 and '22 and our average fleet age has increased as a result. We're -- probably our average fleet age is about five and half years now, we like it to be around four years. And so we'll work on balancing that as we take out some of the older equipment from the fleet and adjusting our fleet, if you will, to the lower shipment levels and that will help from a cost and an efficiency standpoint. But 80% of our costs are salaries, wages and benefits and ops supplies and expenses. And linehaul is a big element underneath that. And so that's why we've got to stay disciplined. We mentioned in our prepared comments about our linehaul load factor being down like it is. I can tell you that's a focus, that's a lot of dollars, not only from a labor standpoint, but that's what creates the miles that we run. And so that's -- we can drive some improvement there, that will help us from both labor and fuel, in particular, while we're also making some adjustments on the fleet that will help with both depreciation and maintenance costs. But like I think I said earlier, there's an element that becomes fixed -- about every variable cost is fixed in the short run. And if we want to continue to deliver service and we are, there becomes a fixed element within that linehaul component. And so we've got to be able to do both, frankly. We're not going to lose our focus on giving service but we've got some room for improvement. And that's what our team talks about every week and frankly, every day out in the field is where we can drive some efficiency. That's going to be the biggest self help area. It always has been. And that's the work that we've got cut out for us as we go through the last three quarters of this year. I think I've said before that when we look at our direct operating costs, these variable cost, productive labor and ops, supplies and expenses and so forth, even in slower periods in the past, even in 2009, we were able to generate some improvement in those costs as a percent of revenue on a year-over-year basis. And so the operating loss in '09 being with our fixed overhead cost, and so that's the challenge that continues to be in front of us. And in the second quarter, I mentioned, if we can keep those costs at 54%, they were about 53% in the second quarter of last year. So we're going to have a little bit of headwind there but we've got to continue to work those costs down as we progress through the year and that will be the operating challenge that we face.
