Lessons from an Eight Year Old

Last week, Stella decided to teach me about cactus plants which she must be learning about in science. She told me that if you cut open a cactus, it is filled with water. I said that I didn't know that but cacti must be good at retaining water because they thrive in the desert where there isn't a lot of water. She replied, "That's true, there aren't a lot of stores in the desert."
