I know a lady whose husband left her after 35 years of marriage and went off to shack-up with an old girlfriend.
She was incredulous when she later discovered that the girlfriend was teaching Sunday School at a local church.
Not all churches do their due-diligence on screening people apparently.
I found Sunday School Intermediates class to be sexy. Girls were just starting to bud.
I know people just like you mention!
One in particular...the other woman taught Sunday and is a youth leader. She and her married lover would go to youth conferences. I just don’t understand how the pastor allowed her to continue. Everybody knew he was married as they live in a small town.
