So my boyfriend and I don’t live together so he stays with his grandmother and so does his brother. Every time I go into the bathroom his brother twists on the door and if he see it is locked he will still twist on it and not say anything. Now I be thinking it’s my boyfriend so that’s stuff my boyfriend would do. So one time I actually opened it with a towel on and he will say oh my bad. If he see the door is locked why would you keep twisting it without saying something such as is anybody in there. He will keep twisting it until I say who is it then he will say oh and walk off and come right back in less than 10 minutes and do the same thing. It has 2 bathrooms in this house they both are full bathrooms so I don’t understand. Am I tripping or is this weird ?
