Well Alan, this is Doug. That's I think about 10 or 15 questions. So listen, I don't actually look at it as decelerating, actually I am quite pleased with -- regarding our backlog, 56%. We obviously have those sales in backlogs, and a lot of those people are all set, ready to go. Obviously, there is timing differences between community openings and closings, but overall, when you see unit delivery, revenue and earnings growth in the double digit fashion, going into 2018 compared to 2017, we are very pleased and very excited about the growth from 2017 to 2018. As far as the demand, as we pointed out, the first weeks we continue to see strong demand. Anecdotally, as we talk to our sales teams, some people are definitely going to hop off the couch and get into the sales office, because of the perception that rates will continue to increase. Our buyer profile is less immune to interest rate changes compared to the entry level buyer. 30% of our activity is entry level, and the balance is between move up, about 52% in the balance luxury. So we don't really feel that interest rate pinch right now, and historically, you see a nice little surge, and then as you look back into some of the previous cycles that I have seen, and I go back to 1999 and 1996, you tend to see a little bit of a decline, but then you see an increase in volume, and with the demand supply characteristics in the housing industry right now, we are very excited about this year and the growth potential. We have got a lot of new communities coming on in the second half of the year. Tom, do you want to add anything to that? It's a lot of questions from Alan.
