This reminds me of the last several months I was still "in" when I had one eye on the exit.
I hated going out in FS because I felt like a hypocrite; I wasn't about to try to convince somebody they should join this religion or read any of its literature. When forced to work with somebody, I'd read a scripture from the Bible and that was my presentation. Thanks for listening, have a nice day. Whenever I could, I'd maneuver the car group so there was an odd number and I'd work by myself. Thoughtful elder taking the lead . Then I'd walk quietly up to the door, press my finger on a spot on the wall near the doorbell, and stand there for a minute. Sometimes, if dubs were walking by or across the street, I'd repeat the process. Then I'd mosey up the street to the next door and start over. This usually went on for about 20-30 minutes, and then somebody would suggest coffee and away we'd go.
It worked for a time, but I don't think I could have done it for very long. Such a waste of time. Of course, that's what all FS is.
