Sure, John. And I would only expect that type of question from you. Good one. So there's a lot of learnings, I'd say, John, on the cost side. The first one I'll touch upon because you go through the crisis, this is a question you've asked us for 15 years, 20. Do you have flexibility in your network in order to handle? And I think what we found out -- and I'd have told you, yes, and I guess I didn't really know the answer, now I do. The truth is we did a tremendous job. Our teams are so talented and the tools that we have to do it. And I'd say through the learning process, what we found is that we probably weren't utilizing the clustering concept to the maximum benefit because we got in positions where we said, we really don't have enough part-time labor or they're not available. And I said, we probably did a much better job of sharing resources than the company has ever done, partially out of necessity, but partially out of nimble local management and just being smart about it. So I think we learned better how to utilize our labor force through this process more effectively. The other thing is we have a lot -- and this is a corporate America issue, a lot of travel and entertainment goes into almost 25,000 employees. I think what we learned is when we didn't have it, we did pretty good. It doesn't mean we won't have it going forward, but I'd say the levels as we think about those types of things from travel and entertainment, to seminars, to ways that we leverage marketing or leads, we learned a lot in that piece. And I think, again, I touched upon it earlier, you'll probably see -- we've really driven down the cost per lead, and we're utilizing digitally much more effectively, which are a lot cheaper than our traditional lead method. So I think we just found better ways to operate as we move forward. And on the backs of that, John, I think what's interesting because these are all things that we did with existing technology. We're now in the midst of what we call a reimagined project, which is taking -- leveraging technology to the next level. It's really every facet of service delivery. So we've accelerated a lot of that through this crisis to try to get there even quicker. And that's going to allow us, I think, again, to become even more efficient, more effective. And most importantly, I think more nimble in delivering service to our client family. So a lot of good news around that. And I think there's near-term benefits that will benefit '21 and '22. I think longer term, reimagine will allow us to further leverage our cost structure.
