My toddler had a respiratory issue several days before Christmas. Hospitalized for a few days. Released a few days before Christmas. We got home. Pipes froze that very day, for several days. So no water in the house. We were supposed to travel, but due to the hospital and weather were stuck home, so we had to scramble to get a few Xmas things together for the kids. Luckily midway through Xmas, the pipes finally thawed - Christmas miracle, we could shower.
Or we understand that a lot of the criteria is just a wishlist, and as long as you meet a significant chunk of it, the rest can be learned in the job.
