Well, I start off with the big picture, which is slide 16. And every year, when there's work to do, we get after it, and we flex our CE WAY muscle and find savings opportunities, and then we reinvest it. And so, again, we've positioned well for 2021. That's the broad message, I mean, specifically from a sales perspective. Residential sales, as we talked in Q3, and still here in Q4 are a bit sticky, as people are working from home, and many schools are still virtual. But as we see this pandemic playing out, we anticipate that those will decline, as you might expect as people go back to the traditional workplace. And as kids return to school. Also, we expect the commercial sales to grow a little bit. Restaurants have been opened up here recently, some limited capacity, but those will continue to grow, particularly as vaccines is more readily available and distributed across Michigan. And so, again, there's not aggressive assumptions in there. It's very conservative assumptions, as you might expect from us, and really returning to some pre-pandemic levels, just as we shared. From an O&M flex perspective, as I shared earlier, we feel like we're well positioned for 2021. We've done a lot of reinvestment for our customers at the end of the year toward to the tune of $0.18, that only helps our customers and provides benefit, but it de risks 2021. Now, the weather could be mild in the winter, it could be a cool summer and there's still pandemic out there, but rest assured what we do each and every year is we don't reset, we don't carve out. We get after it and we flex that CE WAY muscle and deliver. And so, no matter what the year throw at us, I'm prepared, we're prepared as a team, and I'm confident in the guidance we've provided.
