Well, I think the -- first of all, John, no customer, particularly the closer you get to the end market, no customer likes price increases. They don't like getting them. We don't like giving them. We don't like getting them ourselves. So nothing really is changing that in that. But I think the volatile commodity market is sort of owned a new chapter, I think, in a sense it opened a new chapter in customer relations. Customers understand this stuff. They watch it themselves. They're global players. Many of them play in these commodity markets themselves, and they understand the issue of commodity inflation. So we go to them. We have people who are extraordinarily good at this kind of customer relationship. We work on the basis of no surprises. We try to warn customers early. We try to tell them what we're suffering, and therefore, I mean, in the end, it may not necessarily make them anymore sympathetic to our case, but at least they understand it. And it doesn't cause the kind of reactionary negative sort of feelings that you might if you didn't have such good relations. SO I think, John, that it's likely to be a feature of the world going forward I would say. But of course, what it also does for us is there's a constant drumbeat in our company of trying to find ways to reduce the impact of these things, substitute materials, different materials, lower usages of those materials, that kind of constant pressure cooker that we have in our company to ease the impact that these sort of things have on us and then ultimately, have on our customers. So I don't think that the -- I can't expect it to go away, but I think most of it is being conditioned to the fact that this is a kind of the way of the world. Now to come to the last part of your question, which was how can we avoid this kind of delay. I think it's a structural issue in our company, John, that the procurement is separated from our operating divisions, and also we have relatively long supply chains still. They're shortening but they're still relatively long. And before you see the impact in our P&L accounts, it tends to be a sort of a somewhat several month delay. And about the only way that we can really, I think, improve this is to be a lot more vigorous of putting in prices probably before we actually see the impact in our P&L for these individual divisions. So they may be kind of an operating philosophy change that has to get made by us, but they would be things I would to offer to you.
