Have you noticed how certain trends in the congregation are often started by one person, and then it spreads to most of the congregation. For example, in my congregation years ago, just about everyone had a Dodge Airies. That was an inexpensive popular car in the service then. Then after that an influential elder had a VolksWagen Jetta, and then everybody bought a Jetta. If pioneering was popular, then many pioneered. Most witnesses lived in appartments, but then one bought a house, then two, three, and now most of the congregation are house owners.
