Locked In The Basement
My ex called me in a panic because she had locked herself inside her basement. I walked her through using her phone as a light even though she was too petrified to move. I calmed her down and talked her through the process of opening the storm doors from the inside. (there is a latch) I needed to provide a picture of a latch in order to convince her of what she should be looking for.
The entire process from convincing her to move to the other side of her basement to opening the door was about a half hour of steady negotiation on my part. After she got out she described it as the most terrifying experience of her life. She also apparently had the key the entire time but forgot because she was too busy panicking.
