In many cases, it seems as though the elder's wife is more hung up on 'protocol' than the elder himself. Sometimes this is the fault not only of the religion but a manifestation of whatever dynamic exists between the wife and her hubby. For some reason, she becomes his little Rottweiler and seems compelled to defend his sphere of influence. Add to that the Enforcer mentality that many elders' wives seem to have, and it all adds up to the B-word with a capital B.
One thing that might also be at work is this - women among jws have no authority. And of course, they are always reminded of being in proper 'submission' to men. This frustrates many of them, who seek to exert some authority in some way. When hubby becomes an elder, this gives them an opportunity to throw some weight around. This also may partly explain why some elders' wives seem much more judgemental than their husbands.
