AIO for wanting some privacy with my boyfriend’s family and asking them to close the guest room door?

My boyfriend’s dad is visiting and staying with us through next week. And for whatever reason, he insists on sleeping with the guest bedroom door wide open. His mom does the same thing when she visits. It drives me nuts.

Like, 1) I have to tiptoe around the kitchen every morning trying not to wake him (the guest room is literally right off the living space), and 2) it’s just straight-up weird seeing his shirtless dad in his underwear lying in bed— door wide open like we all asked for a view.

I’ve mentioned it to my boyfriend multiple times and said it makes me uncomfortable. I honestly think it’s basic manners, but he brushes it off every time like I’m the one being extra.

Is there a better way to handle this? Or AIO for thinking it’s just common sense to, I don’t know, close the door when you’re a guest in someone else’s home?
