I remember going door to door with some of the friends when I was a teenager. One dub friend I would work with in the ministry, to look good he would pretend to knock on the door and just hope no one would come to the door. If they did he would just say I have the watchtower and awake magazines, he might as well said, "you really are not interested are you?"...
I always hated the time thing as to me most of the dubs were not doing it for the right reasons but only to pad their monthly totals. My sisters when they first met my girl friend were as nice a pie to her, only to ask her to attend a meeting or assembly. I warned her that they only look at her as a potential bible study so they can just count the time on their ministry report.
