Yes, I'll come to that. Let me go a step further beyond Professional Lines and commercial auto. We regularly look at portfolios and it happened just last week, a group of us spent many hours doing the deep dive with our casualty folks from around the world, going through all casualty portfolios and giving updates on what we see in pricing and trend. And our updated look at trend right now, it's a -- the casualty-related trend primarily is running around 4%. And so you'll say, well, that's not 5%. And we see the same thing in comp, by the way. And so that's not 0%. And that's my point. While it's still a little tamer than what we had seen historically in the past, you take 4% that goes year-over-year-over-year-over-year and you got prices that are flat or down, well, do the math of what happens to loss ratio and what you do with risk selection, et cetera, and portfolio management or terms to alleviate, that plus expense are your anecdotes. But other than that, it does grind. When it comes to Professional Lines in your question, it is about the external environment and I'll ask maybe John Keogh and John Lupica, who both grew up in the business, to speak, maybe give you a few comments. But I would tell you this. It's not that we're seeing populism. Remember this doesn't happen on a dime or appointments of judges recently. Appointment of judges, that has occurred for the last 8 years. You've stacked a more liberal court, on one hand. But what we're also seeing is a change in the plaintiff bar environment. There are more plaintiff bar law firms, more boutique law firms who are like ambulance chasers and out to make a buck. And it's attacks on society, by the way, it's attacks on corporations and it's a problem where anything that represents any kind of bad news, that is natural exposure to any kind of business, and by the way, this is not restricted to one industry like health care or I read some of that and that's just not right. It's very broad-based. And there's not a merger that goes down where there isn't a lawsuit filed on both sides. You paid too much, you paid too little. And do these get settled? They get settled to reduce its money, but it's still money and it increases the frequency. And then security class actions around absolutely everything. And then employment practices liability, as an example, has found its way into higher-paying jobs, when it seems as part of layoffs today that, okay, another retirement benefit you get or another benefit you get is a payment from an EPS. That's the kind -- that's just what's going on. Now I'll ask my colleagues if they want to answer that.
