Well, Dave, if I'm looking at, and I'd like to look at a kind of pre-pandemic, and what we're currently seeing like if I were to look at large deals in the Class A space, probably pre-pandemic at TI package was probably, let's say, 110 a foot, and today to be anywhere from 130 to 140 free rent, probably, it was right on top of a month, per year. And today, it's probably, 1.25, 1.5 months per year term. And then you have your unused TI conversion, which is probably gone from 10% maybe upwards to 20%. We're not really seeing those types of lifts, I think, we see less slippage in the Class B space. And probably, more importantly, just like in the multifamily space, it's about retention. I mean, I look, just reading with JLL, their deck and retention - excuse me, renewals in Northern Virginia were up one-third. And I think they're more economically - can be more economically viable for both the tenant, and certainly for the landlord. And so we're really focused on renewal, you have to remember, I mean, especially in the lease space, and looking at our portfolio. We're playing in that 4,000 to 6,000 square foot range. And so we're not really competing for those hefty TI packages and big free rent packages. I think tenants are very savvy, and they're going to, obviously, try to negotiate the best deal possible. But there's definitely a spread for the big renovated A's and trophies that have to achieve occupancy and what they're willing to do by occupancy in the Class B's. So I still think there's, we have an adequate delta between Class A rents and Class B rents in the region, Dave.
