That’s probably not going to leave a mark

The OCD’s are next to us for a few nights, seems. They are grumpy buggars who never smile. They do everything outside of the RV: Cooking meals, eating meals, watching TV, etc. It’s as though they do not want to upset the inside of the camper by any means.  Today though they are not pleased with each other and have taken to aggressively launch Kleenex boxes at each other.  What the heck?
