My grandpa has no sense of privacy?

[James Bond]

He's a healthy 64 year old man, and I'm 15. I live with my grandparents. My grandma doesn't knock, like, I was *censored* one night and she just barged in with my clothes. My grandpa, he showers with the door open because he says it gets too steamed up in there. And then after he walks to his room in a towel with his as* hanging out and then changes with the door open. I'll be walking through the kitchen, and there he is in his bedroom with his cock hanging out. What should I do for myself, to get both of them to knock?

Just say to them nicely that you need your privacy, and ask if they could knock before going into your room

Locks on your door or tell them you don't like how they have no privacy
