My sister and her husband are in the circuit work - it is their career and they treat it as such. i feel for the wives who are there for the support of their husband and have to be so careful not to offend, get to close to anyone, stay aloof or otherwise be a reproach or a cause for stumbling. The pressure is enormous.
Think about it - for a sincere, believing dub there is no excuse for not being in the full time work in some way. In the case of my sis, they are the new crop that will not have kids been married going on 20 years and know no other way of life. They take a vow of poverty (for tax reasons) and she was obsessed with not having too many expenses for the cong to cover - ie - repairing nylons. Even I told her that was ridiculous.
They are very protective about their own time and she dresses more in style than most people I know. She is a very "hard" person - ie guarded and i can't imagine warming up to her in a week long cong visit.
