Don suggested I take a shower while he washed and dried my shirt. I cleaned and replaced the trap and soon it was working just fine. I loosened the trap and was about to remove it when it suddenly came free and soaked my chest and neck with dirty water.
I laid on my back and crawled under the sink below the drain trap.
Don let me in and showed me to the kitchen. Usually drains are not much of a problem so I wore regular street clothes rather than coveralls. he seemed like a nice guy, so when he called a week later with a stopped up drain, I agreed to visit his house to correct the problem.
I met Don in a local bar and somehow, during the course of our conversation, I told him I did plumbing work on the side.
