Yeah. I'll give a quick comment and then allow Jack to fill in any blanks. I, -- it's a dynamic environment, right? To say the least and I think that, in many cases, particularly in the home category, obviously Lovesac and like companies have been recognized as perhaps COVID 19 beneficiaries with people working from home and spending money on their home. So, while I believe that, much of our success of late has been due to the agility of the team and our ability to react to the environment. We certainly recognize these tailwinds. And in our case, rather than seeing just increased sales, as many in the category seen in depleted inventories and longer lead times there's so many things I've tried to purchase myself as a consumer that you just can't get right now, or you have to wait much longer than expected. That's not been the case for us, because of the way we've managed it. And so, the results have come out for us more toward the bottom-line, I believe in the near-term. And, essentially I think we've gotten more for less just, obviously, smaller staffs on our front lines, having reduced at the very beginning, buckling down for COVID and also the way that we're spending on marketing our ROIs are certainly high and increasing, partly due to the new tactics, but obviously aided by these sort of tailwinds. And so, long-term for us, our outlook, we would still like to maintain high growth, not just through new product innovation, which will come but also, due to these the ongoing, test and learn, behavior that we've demonstrated for a long time and our commitment to innovation on the marketing front. And, and larger spends is as we get bigger, perhaps, expecting the tailwinds to trail off. And so on the top line, we believe we can sustain high growth. Obviously the numbers get bigger and harder, but that's still our outlook on the bottom-line the company is leveraging and reaching that critical mass where I think, we're able to show leverage, at the same time, we would expect some of that tailwind to trail off eventually and but time is on our side on that -- from that standpoint. So -- and so I don't think that, we're at all ignorant to the kinds of we'll call it COVID tailwinds that are driving some -- some of our success at this moment, but, we haven't let it be a runaway train and just drive self to the roof and deplete our inventories. We've been very careful to manage that. I don't know Jack, if you have anything to add to that.
