Yes, Stephen -- yes, Stephen, thanks. It's a great question. Let me like preface this by saying the following. There's been a major paradigm shift in how people search for travel on the Internet. Before the pandemic, the way search was on the Internet for travel was the vast, vast majority of people came to a website, a travel website, typically an OTA, and they would type in a location. They have a location in mind, and they go to date, and they check -- type a date to check-in, and a date to check-out. So this is really fixed search. People know where they're going to go. With the pandemic, I think it's safe to say the world is never going back to the way it was, and that means travel isn't going back to the way it was. And the way travel is evolving is that people because they're able to work more remotely, they're more flexible. And what we are seeing, Stephen, is that 40% of our guests have flexibility about where or when they travel. And to give you one example of one of the things we've done, flexible dates. We have a couple of flexible date features. We have a feature that you can tap, I'm flexible, and you can say I'm looking for a place for a weekend, a week or a month, sometime in the next few months. And what we have seen is with our flexible date feature, it's being used more than 500 million times. This is a feature that's been used 0.5 billion times since we launched this feature in the beginning of the year. We've also seen a very big uptick in the use of flexible destinations as well, where people -- if they're flexible about where they travel, we can recommend them to where to go. Now these features are really important. The reason they're really important isn't just because this is the paradigm shift and how people are searching for travel, but it's also important because this means that we can point demand to where we have supply. And this is a major, major shift for our business. And so we are going to continue to tweak the products. When you have hundreds of millions of data points on a feature, you learn, and we're continually innovating. But I will also just say that this is just the very beginning because our team is not going to rest on their laurels. We are working really, really hard to continue to offer more flexibility to guests and continue to be able to inspire them and point them to where we have available supply.
