My first solo was in winter, water was 13 Celsius. I had hard time closing the back zipper, whatever I tried it wouldn't go up more than halfway. Frustrated, I extended the zipper line and tied it to a high fence and tried to pull myself away to close the zipper. Some people walking on the beach thought I was suicidal and began to talk me out of it. Was so embarrassed didn't ask them to help me with zipper.Diving solo, having trouble getting out of the drysuit afterward, and needing to wedge the wrist ring in the door jam to be able to pull my arm free.
The dive was short and cold, also placed cylinder on mask and broke it.
