Liberal brother in law & his wife arrived yesterday wearing masks inside the house

I was working when they arrived so I haven’t seen them yet but the wife went over to her parents to visit with them and she said upon walking through the door, they immediately asked a blanket statement to everyone “is everyone healthy?”. They were both wearing masks and continued to do so after settling in. They were still wearing them when my wife left. These two are 50 years old and lifelong “republicans” who voted for Biden. I believe the liberal conversion has been complete and successful with them.

They don’t have any children, don’t want children, and they’ve mentioned in the past that they still use condoms when having sex. I’m convinced she has HIV and is keeping it a secret - why else would two grown arse adults refuse to raw dog it? Sure, they don’t want kids, I know. But there’s the pull out method, vasectomy, and she even can get her tubes tied if they don’t want to have a mistake. Something seems off with them. There’s no other reason two married grown arse adults would still frick with condoms. Combine that with the fact that they are absolutely terrified of covid and my theory that one of them has HIV grows stronger.

I need some really good passive aggressive ways to frick with them until they go back home. What ya got, OT?
