So the bottom for me, Jamie, is when the distribution of vaccines and vaccinations are broad wide and in place. And we've already seen in Israel and in the United Kingdom, where they're way out ahead on their vaccination. We've seen the numbers really dropped tremendously as far as infections. And that bottom, therefore, to me, is based on when people feel, okay, we now know that may be endemic, maybe we get an annual shot. However, we can now plan going forward. So to me, it's a time when people stop on the pivot and flex every single day and say, all right, this day, looks a little bit like the day before, the day before that, and we can anticipate tomorrow is the same what decisions do we want to make. And I think a big component of that, Jamie, is the degree from the leasing market, what we have done long-term leases, there are a lot of folks who have focused on users who are focused on short-term renewals while they reevaluate what goes on. And I think that we've seen that behavior in 2021, we will see it in 2021. We definitely saw it in 2020. I think that will also taper off by Q1 '22. I think people will begin to plan longer term, which means, by the way, that the normal roles, which you'll see in '22, '23, '24, people who have roles coming in '22 and have kicked the can down the road, they will already have done that by Q1 of '22. So people will now begin to plan for '23, '24, '25, '26, along with all the other short-term renewals. And that to me will set the stage for resumption of leasing probably with a vigor, real vigor, but I think in '23, '24, '25. And then the last thing I would say is that was a bottom due to the the wide distribution and uptake of the vaccine, not only will people return to offices, but when they return to offices, those commercial districts, which have had retail so badly impacted, the retail will know where it is and have a certainty and ability to open. Good news about the U.K. from a tourism perspective is the U.K., at least in the Empire State buildings, are number one source of overseas visitors. So as the U.K. vaccination gets way out ahead of everybody else, I think with vaccinations, you'll see more normalization of travel. So New York has a hospitality center. New York City is a hospitality center. Again, Q1 '22, I think those are positive, certainly from an internal United States travel perspective, and we'll begin to see glimpses from international, so I would say, across the water. So that's what I think about when I say Q1 '22 bottom.
