Venus: Have you noticed the funny smell in your shower?
Venus: Have you noticed that there is something growing in there?
Venus: Don't you feel strange about stepping in all that slime?
Mars: Green stuff?
Venus: Doesn't having a clean place make you feel good?
Venus: Never mind. Let's talk about science.
Venus: Mold! The shower is full of mold!
Mars: Is that what that is?
THE LIGHT BULB MOMENT...WAIT FOR IT
Mars: If I step on that stuff will it get on my toes? EEEWWWWW....
Venus: Please buy some Clorox.
Venus: That the only thing that will kill the mold.
Mars: Isn't that really bad for the environment?
Venus: Hoisted by my own petard!
Mars: What's a petard?
Venus: None of your business. One teaching moment at a time. Go online and please find out what kills mold besides bleach. And don't give me vinegar. They always say vinegar. For everything. If it isn't vinegar, it's baking soda. But none of it ever works.
Mars: (with a pitying, worried look...) Sure. Sure thing.
