I remember when the article came out. My (now ex-) husband who was the lush of the land, a secret daytime drinker, nighttime pornography viewer, and one who made it a point to have beer at dinner on the way to the hall while the rest of us always decined, decided he would stop for 30 days but didn't tell me about "the challenge". When his month was up, he pointed out to his elder buddies that I continued to have some beers of an evening and made it sound like I had NOT been able to stop like he did. What a jerk. So glad he's gone, better that he remarried and got (briefly - daddy an elder) disfellowshipped for adultery/not being "scripturally free". He's a shining example of jwdumb.
Not suggesting that anyone on this site would do this, but please be careful about using these types of admonishments as barometers of anyone else's behavior. Jdubs love to treat suggestions like this as rules, and that stuff can stay with ya.
