Let me take a shot at that. This is Fred Smith speaking. First of all, I think it's important to look at the things that we've said over the last few earnings call in the context of about what's going on globally. I mean, I watch the business press every day and I have to tell you, I think there's a lot of whistling past the graveyard about the U.S. consumer and the United States economy versus what's going on globally. So, the serious trade dispute began in the spring of 2018 and they escalated throughout the summer of 2018. And most people don't think about the fact that when China slows down because of U.S. tariffs or uncertainty or for whatever reason, as big of a victim, if you want to call it that, of the China slowdown is Europe, because Germany's contraction is because they're not selling as much to China, which is a huge customer of Europe. So remember, last spring, there was a tremendous amount of euphoria when we were going to get a deal, China trade deal. And then at the last minute, it broke up and then over the period of the summer there have been escalating tariffs on both sides and increasingly lowered industrial production and that's why we’ve put those charts up on the IR website. So we're reacting inside of FedEx to the same thing. So as we went into the fiscal year, we were hopeful of a trade deal and some sort of restoration of normalcy that has not taken place. And the U.S. consumer, which is a remarkable driver of growth in employment, and all the things that are spoken about every day, sort of mass the fact that the goods producing sector, which we're in the midst of is much more global in nature than the U.S. consumer, which is largely services and certain consumption. So that's the reason that we began the year the way we began it, and should we have moved faster or known faster or what have you, I mean all I can do is report the numbers as we see them. And I would point out to you that last fall, we were the first people that call this out. And I remember very vividly. I mean, we are the leading prognosticator of this, we have 15 million votes every day in our system. And I remember when we made this call on CNBC, they took our heads off that we were, “blaming someone.” We're just reporting what's going on and reacting to these macroeconomic things. And as Alan said, that's why it makes us so hard to forecast. We think we've taken appropriate steps. We'll do more if we have to, but I can't give any better answer than what I just did.
