Why is your mom bringing guests into your bedroom?

Would your name be Janie Briggs, by any chance?

Now that's what I call a sticky situation

Hopefully that will teach her to respect your privacy

well what happened afterwards?

Why would you bash the bishop when there are guests in the house.

That’s what I was wondering. Maybe they were there too long and he thought “fuck it.”

They weren't the OP's guests and they weren't expected, generally speaking, to interact with the guests. So, hid in what they presumed was their private space, started to take advantage of that, and learned, to their dismay, that mother 'dearest' has a boundaries problem.

Did you finish?

Well, does no one know how to knock anymore?

Lock the door or take a shower if you have no real privacy in your room.
