I cannot pee with the door open.
There, I said it.
I have been married over 11 years and I still have trouble peeing with the door open. I get the stage fright. I don't like anyone infringing on my personal time.
When my kids were little, I would be forced to pee with the door open during the day because you just never know with kids. I liked to be within ear shot. Then, as the kids got older, I started closing the door. Now, my bathroom breaks go something like this...
Me: Running upstairs as quietly as possible so I don't draw any attention to myself.
Kids: They can feel my presence lift from the room. It's their sixth sense I swear.
Me: I make it to the door, shut it, and quick lock it for safety. Business proceeds.
Kids: They get an instant need for my attention.
Me: thump thump thump... I can actually hear them coming for me!
Kids: Moooooooom! I need to talk to you! Are you almost done yet? What are you doing in there? I really need you right NOW! Come on Moooooom!
This all happens within a matter of seconds. It never fails. So, my bathroom breaks are clipped to a minimum. It's no wonder I like a little alone time with the door shut.
Oh, uh wait... excuse me for just a moment, I need to use the little ladies room. Shhhhhh, pleeease don't tell anyone!
