A mouse interrupted my session once... There was this scrabbly scratching noise happening every now and again... We both tried to ignore it at first but eventually it got really intrusive. It sounded like a dog or a cat or... something... scratching on the door, so T stopped and was like "sorry, I'm just gonna look..."

Opened the door and looked out and of course there was nothing there. The "wtf" look he gave me was amazing, and I was like "don't look at me, it's your house!"

He later said that it had definitely been a mouse and he'd humanely trapped it and taken it elsewhere. I said I didn't mind it joining in my therapy... hah.
