Well, in today's world, it's just been utterly crazy. changing the way we learn is been a whole new facet for every school and every education facility across the world with work from home remote, all the interconnections that kind of spurred from government closings, to mandates, and everything in between schools have had to adapt to technology and new thinking, new new processes of how we do everything, our students, and the connections have to be real and stable. And so we've had to lift and shift everything from this in person immersive learning to this new online experience. And the experience has to match up whether in person learning, and without having that kind of connection with people. It does not succeed. So schools have had a massive challenge, especially in the last six months to the last year on remote learning, turning everything around and doing now hybrid learning as we've been coming back in the fall for school learning, how do we immersively captivate everybody's attention not only in person in the class, but those that are comfortable are not able to attend in person learning to be as inclusive as the ones in front of you. So there's been lots of challenges, and the only way to be successful is to have a good working infrastructure across all facets of the organisation.
