Well, it's hard to get a barometer on the pre-pandemic levels because I think people have in their mind this notion of 100% benchmark, which is far, far from the reality of what space utilization is. And as best I can tell, anecdotally speaking with all of our tenants, which isn't the bad samples [ph] we have, 900-plus months tenants is that between PTO and holidays, sick days, traveling, people travel for their work and -- did and still will. And there was an element of remote work even before the pandemic. It's not a completely new science that an average day would be somewhere in the 70% occupancy range. We can't - I don't have hard statistics on that, but I can tell you that I'd say everything I hear is either right at that level or in the 70%, 75% level at max. Some companies are different, they have higher capacities and some are less. But that - I think that's a good average. So, when we talk about approaching 50% occupancy, physical occupancy in the near term, that's a good ways back. And what it will take and how long it will take to get from that 50% to that 75%, I think that's just, as I said earlier, it's just going to be a matter of working through the disruptions of the system. And a, recognition that many firms will, at least for the time being, work some increased element of flexible remote work into their program, but we're still hearing almost across the board that the majority of days will be in the office, so whether a company is going to go to a 3-day work-week in office, 4-day work-week, and 5-day averaging, maybe 4 days or so, everybody has a desk, everyone's got a landing station and these same companies that are talking about some element of hybrid work model are the same ones who are signing 10,15, 20-year leases and generally expanding. I think our expansions out number our contractions by like 521, that's in terms of square footage and maybe 421 in terms of number of deals. So, the larger deals, it's even more pronounced that the expansions of our number of contractions in our portfolio, 421 or 521 and we looked out over 200 transactions. We did 200 and some odd leases in 2021, that's just office leases. And so, that's a very good sample set. And I think that this year, the confidence factor is going to be even higher. And we have a rising occupancy. So it will, I don't know if it's going to have an impact on our portfolio. It is going to have an impact on the way companies work and I think it's an impact for the better. It's part of this whole shift in what we deliver to tenants being not just a delivery of commodity space. We never approach it like that, but now more than ever, we are going to make every effort possible to demonstrate leadership in this industry by giving workers every reason to want to be in the office, maximum efficiency, health, safety wellness, food and beverage amenities, lounges, town halls, some fun, recreational items. workout, spa, wellness, it's all part of this new package of delivery. We're working into every one of the buildings we own and the feedback from tenants and tenant employees is that they love it. If the vibe is great, people have more incentive, they feel better and I think we will over time get back roughly to pre-pandemic levels, but for whatever kind of shifts there are, that might insert more remote flexibility, but I don't think there's any question in my mind about the office as the central hub of everything that takes place in the workplace, and the sense of community mentorship training and business generation, I don't see that being degraded, but time will tell. And we'll see the results, but the early indicator for me is the leasing and the leasing right now both in terms of the 1.9 million square feet we signed last year and the 2 million square feet we're projecting for this year, we think says it all.
