Thanks, John. Good question. So, a couple things. So, first, I think you have to really put our Q1 gross margin performance into context. You know, both in terms of the history of our first quarters and then, you know, a lot of unique stuff happened in Q1. So, let me talk about the history first. Historically, Q1 hasn't been a good gross margin quarter for us. If you look back to 2019, for example, it was our lowest gross margin quarter of the year, about 80 basis points below are our full-year gross margin. So, you know, why has Q1 historically been a little weak for us? Well, you know, we've usually turned inventory slower in the first quarter. Usually we've carried over some clearance merchandise from the fall, which has a tendency to hurt our transition into the spring. Now, let's take a look at Q1 of 2021. Very unusual to say the least, we put up [a 20 comp], executed incredibly fast sales chase, and increased our inventory turns by nearly 60%, unprecedented improvement, and one that would be very difficult to sustain. So, these extraordinary turns are not something that we would ever plan for. And they were driven by way ahead of planned sales. And back in Q4, we also benefited from chasing ahead of planned sales that helped us to end Q4 with less fall merchandise than we would typically have. So, there was less to markdown in Q1, and was easier to transition quickly to spring. So, that's kind of a long way of saying that we had plenty of room for improvement historically in our first quarter. And we just put up a quarter, that'd be very difficult to replicate due to all the unique circumstances we have this year. Having said all of that, we continue to believe that we still have further room to reduce our comp store inventory levels, which should over time, reduce our markdowns, and drive even more improvements in our merchandise margin. And we would also expect that trade expense over time would normalize and put less pressure on our gross margin in the future. So, let's not extrapolate from one unusual exceptional quarter. We do think we can continue to make progress, but it's going to be really hard to predict that pace until we get into a more normal environment.
