When I was more in “the truth” I knew of certain people that were not allowed to be put in the same car group by the person making the arrangements.
In both instances they were sisters that were not supposed to go with young pioneer brothers
I was told not to assign 35 year old married sister with pioneer brother 25 year old. Then the elder said to me don’t put her with any unmarried brothers
The other time I overheard not to put 45 year old horny pioneer sister with 30 year old mts brother. They had a thing going it was common knowledge but swept under the rug as they were both circuit stars
