Yeah....(blush) I did this too.
I had been laid up for quite a while with a bad injury and when I was off the crutches and out of the wheelchair---I was "encouraged" to join the older ones for this thrilling afternoon activity one day a week. We got dressed head to toe in meeting clothes (wouldn't want to insult Jehovah by wearing slacks and a nice sweater on a winters day) and we sat around a JWs dining room table, passing the phone around and going into our WTS-approved speil. I can't recall that ONE JWs got a return visit OR was able to place anything.
I spent a LOT of time writing letters.....for many years. We have long and very rough winters here and to "keep up my hours" I often resorted to doing this. I was by myself....and did not feel it was mandatory that I dress in the usual meeting clothes.
