I understand how your wife feels. I was a hardcase with my husband for not keeping the kids quiet too. In fact I used to berate him for not taking control like I felt he should.
With the benefit of hindsight I can now understand how much is put on the believing wife to have her children and family well regarded and classed as good associates. The pressure is huge. In turn us girls transfer the pressure onto our husbands because they are supposed to be taking the lead etc.
So the kids are ratty and bored due to unrealistic expectations from the parents. The husband is ratty due to unrealistic expectations from the wife, and the wife is ratty due to unrealistic expectations from the congregation.
Problem is, the wife can't blame the congregation because its Jehovah's mouthpiece, so the husband gets it in the neck instead - sorry guys!
Memorial is best avoided. Better still, keep the kids home with you too if you can.
