So, thanks, Greg, this is Joe. I'm going to take a shot at both of these. Look, I'm all in favor of the concept of the world changing and new pieces of the economy coming forward. I think some of these tech startups, they're taking a narrow piece of the business and thinking they can revolutionize that and they're missing a big part of what actually runs on insurance. And that's actually managing the cost of goods sold, which is the loss costs. I don't think most people look inside of the numbers here and think that solving the expense ratio, or enhancing the expense ratio in our specialty business is what's going to lead us to be way more effective in terms of what we're doing, we already have a leading expense ratio inside of that space, it's about understanding the loss costs and managing those there. And we're really, really good at that. We've been growing in some of these geographies at fairly significant rates for a long time. These are short tail businesses. We already would be seeing a temperature if they were coming there. So what we're doing is, we're doing very thoughtful things with our specialty model with our pricing, with our sophistication, understanding the market and we're highly confident that it's a sustainable model. Now, the caveat on that is, we've been talking about it for two or three quarters, that the frequency levels that we're seeing in the industry are not sustainable. We do expect they're going to go back at some point to a pre-pandemic level. And when that happened, and that frequency runs up, these combined ratios are going to go up because people are actually back out driving more. We never suggested that anybody should be expecting a combined ratio in the mid 80s for a long period of time. We told folks we're targeting in that more mid 90s, that's where we'd expect to be at a fair return for our shareholders, a fair return for our customers, nom and grow as much as we can, we think it's a little bit of a wonky environment right now. And we're trying to constantly make the adjustments through the pandemic environment. So I don't want to have a misstated, quote, come back two quarters from now when we see that combined ratio rise. If it's coming back from the basic set of frequency, as people return to “normal” whenever that is, that is going to happen, you should expect that to happen. It's not going to be because we don't know what we're doing in the states and these geographies, we're highly confident there.
