I overheard two kids arguing as they were walking in from the back patio, so I asked them what the problem was.
Kid 1: “Is grass a plant?”
Me: “…Yeah… of course it is. Why?”
Kid 2: “He said he was gonna water the grass, I told him that you only water plants.”
Kid 1: “Yeah, can I go water the grass?”
Kid 2: “Dude. Nobody waters grass. I never seen nobody water grass.”
Me: “Yes… uh, yes they do. What do you think the sprinkler out there on the lawn is for?”
Kid 2: “Not for grass. For plants.”
