Guess I need to start knocking
My mom has been single since I was six up until about two years ago, Six months ago she got married and two months before that my husband and I went and stayed at her house as we used to often.
I woke up in the morning and heard my mom get out of the shower and go into her room, I got up and used the bathroom, Went back to my room and then went to talk to my mom, I didn't realize her then fiancé was already there since it was only eight in the morning but I have never had to knock, I just always walk in and it has never been an issue before.
Well...It is now, I opened the door and frick, My mom was sitting on the edge of her bed with her house coat on and he was standing in front of her with her giving him you know what, I screamed, He screamed, She couldn't and I slammed the door.
I went to my room and told my husband and he still laughs about it, My mom came out to the kitchen and we had a very embarrassing talk about how I should knock from then on.
