Okay, so a lot in that. Our positioning relative to the mix of our buyers hasn't really changed appreciably in the last couple of years, and it's not going to change very much in 2019, somewhere in the 55%-60% range were our first-time buyers, about a quarter or what we call active adult but are also empty nester buyers. And I have to point out, a very small percentage of those buyers, in '18, were actually in Gatherings communities, but the portion of our active adult business is going to twist towards or grow into that Gatherings mix over the next few years. But you can serve that active adult buyer with single-story ranch plans that are modest in price and high in livability. So we've been roughly 80% in those two cohorts, and I don't see any real change to that in the near-term. In terms of how we withstand the competition, I don't mean to be a smart aleck, but it's a home game for us. This is where we are. This is who we are as a company, it's what we know how to do. And what are some of the things that we do differently. Well, it's easy to talk about construction quality, but you get a HERS score or an ACH report an ENERGY STAR Award, these are bona fide third-party verifiable, factual things that we can demonstrate are different about our homes that affect their livability, they affect the monthly cost of occupancy, and their long-term cost of ownership. I mean, we do things in our homes that other entry-level first-time buyer builders don't do, from house wrap, to framing techniques, to roof underlayment, to the quality of shingles we're putting on the home. And honestly, those things are a little hard to explain on an earnings call, but you start talking to a first-time buyer who has waited to acquire their home, they've become more sophisticated, they're well educated online, it's very powerful for our sales team to be able to talk about those differences. And then we put them in a mortgage program where they understand that there is a real effort to serve their interests, not our interests. And I think those are two big things that differentiate us and are very palpable to any buyer in any one of our communities.
