I love it when suits and dresses with fake smiles call. I always get a chance to divulge the fact that I studied with them many years ago. Not a lie -- I simply don't expose the fact that I then became a MS, an elder, developed a bothered conscience that resulted in disfellowshipping.
Their inevitable question -- "Why did you stop studying?" -- is the perfect lead to my introduction to The Great Watchtower Contradiction, an 11 minute read designed for new ones but which poses questions on topics that the most seasoned JW -- your husband included -- would cringe at.
Contradiction contains a table handout that you can snip for purse or billfold. I always keep my billfold handy.
