Yes, Dave. I think it had to do with -- first of all, every situation is different. I'm not sure that when you get to historical precedents, everything is a little different. Remember, this is always in a quarter. We're talking in a broader scheme of things. This is a blip on the radar screen, ultimately. So the reality is, I think, that the analysts have become so focused on all the moving parts within the quarter, and they ascribe great value to individual movements and new lease rates, renewal rates, occupancy rates that is really beyond the scope of what you can manage, all within a timeframe. Because again, as I said earlier, what you might do as an owner of a portfolio over the long haul can be significantly different than what you might do in the quarter. And that topic of conversation is one that Erik and I have revisited many times over the last 30 days, because he's -- we are focused on cash flow and revenue. And practically speaking, given the quarterly result thing, you may have limitations on what you can do in terms of how far you can move occupancy down in search of higher rents, for example. So I guess from my perspective, there was a pretty sudden change in consumer sentiment, as we said before. Our division managers would describe it or do describe it as effectively seasonality starting a month earlier. I think it's just related to the results, the things that happened in early August. And I think everything is -- every situation is a little bit different. And so I'm not sure that history is going to help us with this. What I also can say is, our reaction to changing conditions -- and again, we're not talking about, oh gee, the market went from being great to being horrible. We're talking about a shift of sentiment, a shift of preference and that type of thing. It doesn't change the broader picture here. And I think that we could have reacted faster and better to build occupancy quickly. One of the issues, we were a little bit more -- we had a smaller portfolio, a flatter organization than we do now. And it was easier to implement change than it is now. So that is something that we are working on and will be the focus of a meeting that begins immediately after this conference call.
David Bragg - Zelman & Associates, Research Division: Well, I understand the preference for focusing on the long term. I actually think that, that's a point in my question is that given such a robust outlook, 28% rent growth over the next 5 years, people are looking for evidence of that sustainability or evidence that there may be weaker demand than expected. So on that note, just thinking about your 5-year model, what level of household income growth is embedded in that? And how important is that component to the model?
