Never mind the donors to sarah pac right and that very expensive customized bus.As was said earlier... she apparently takes the idea of jury duty as a 'duty' more seriously than others do.
I'm not surprised you fault her for this. I have no doubt that if she had requested to be excused, you'd be all over her like white on rice, claiming she is more interested in her vacation than performing the dities of a good citizen.
She has a perfectly legit reason to be excused. That any person would use.
Try telling your wife you have to cancel your vacation to Hawaii with a non-refundable deposit because of jury duty.
