After a session with an SP, I showered before leaving her apartment.
I had taken off my watch in the shower, and placed on a high ledge of the stall.
After I left, I realized I had forgotten my watch, so phoned to be let back in. No answer.
Keep phoning, and get no answer.
Another resident saw me outside and let me in, and I knocked on the SP's door. Again, no answer, and now I was stuck in the hallway with nowhere to go, not wanting to create a disturbance banging on her door, so I went back outside and kept phoning.
Took 40 minutes before she called me back. Turned out she decided to relax in a bath after our session, didn't take her phone, didn't hear me knocking and never saw the watch.
We laughed about it afterward, but was stressful at the time.
