 The more kids need to know how to swim in general, and you're here to do it, and you should be providing that. We need more kids helping them learn how to swim. If you're not providing it, and you are in the aquatics business, that is a money loss that you have, okay? Best ways to do this is one-on-one, because they learn faster. You can do it in groups of two, okay? Usually if they have siblings and they're close in age, you can do it in group of two as long as they don't mess with each other. You can even go in group of three, okay? But after three, you get some kids, depending on where you're at, hopefully you're in four feet or under. You want to learn to swim in four feet or under, okay? So that kid goes down, right? They can bounce back off the bottom where you can grab him. All right, you can transition to deep water once you feel comfortable, but not with more than three.
