Isaiah doesn't like to be alone when he does his "big job" in the bathroom. As such, he's decided that I don't like to be alone and he needs to keep me company any time he's here and I excuse myself to go to the restroom.
Isaiah, shut the door. I'm trying to use the restroom.
Just a little bit, Grandma. I don't want you to be alone.
But, I want to be alone. I don't need company and I don't need to leave the door open.
If you need anything, you just call me and I'll take care of it for you.
Thank you, Isaiah. I'll be sure to remember that.
