same family, different evening at the pool

yesterday, I was swimming and the same family was there. The girl was holding a little bottle and told her brother; "you got chlorine in it." He asked; "What's chlorine?" I said; "it's the chemical used to clean the pool or else it will be green because of the algea." Later on, the girl said; "I broke my toe." She was moving quickly so I said; "if you broke your toe, you couldn't move, you would be in excruciating pain." She said she hit it on the lights in the spa. The spa is really hot and has lights underwater which of course are very hot because of not only the heat of the water but the pressure when you turn on the Jacuzzi to generate bubbles. I told her; "it stings for about a few seconds and goes away then you forget that you even had a burn."
