Well, the way I'd characterize it, Jeff, is not that the performance doesn't hold, but as an example, much of the close to half the performance, our performance came from better than we had expected performance in our full service business in the U.K. And that is coming from, solid enrollment, continued good, both cost management, labor management, and effective protocols on recruiting retention there. And we're now getting to a place where we're lapping the effect in the UK had introduced expanded funding to parents as of April 1st of last year. And so, that contributed to some of the enrollment velocity. So, enrollment is very strong. It's been strong the last few quarters, and it will continue to be solid through the rest of the year, but not quite as much velocity as we saw in Q1 in the last couple of quarters. So, that's beginning to bake itself through the comparisons. And, you know, I think from an overall performance standpoint, we just have stronger performance in the first half than the second half, and we'll be lapping the strong, the rest of the overall performance in the U.K. So, that's, it's not worse performance as much as it is just where we will be comping and what we're growing off of in terms of the base. The rest of the backup, I think I mentioned before, we had really solid usage and effective cost management, service delivery, and a good portion of that use in our network and being able to manage those components, and it was somewhat favorable to our outlook. So, those were the drivers there. I think the forward view is certainly reflective of what I just said, and then, you know, wanting to take into account that the environment is certainly still settling and uncertain from a macroeconomic standpoint. And in backup in particular, we have a disproportionate amount of the business that comes over the course of the late spring and summer period, and that is still to be delivered.
