What if?
Assuming that a “lifetime” is equal to eighty years or so, what would be different in our meetinghouse a lifetime ago?
Well, the driveway, unpaved, would be dusty in summer and muddy in winter. There would be no electricity in the meetinghouse, but there would be four coal stoves. Two would be located on each side of the partition that separated the men’s and women’s meetings for business. There would be no classrooms upstairs and to reach the Annex you would have to go outdoors.

If a Friend of the early 20th century could travel seventy-five years back in time, how would the meetinghouse seem different?
There would be no Annex, no piano, no porch, but there would be two cemeteries and a brick wall separating the meetinghouse from North Main Street. The interior would be considerably darker because it was not yet painted white. The entire floor area occupied by today’s facing benches would be outside the walls. No one would ever have heard of Friends Village.

And what if that pre-Civil War Friend could “visit” the monthly meeting of a “lifetime” previous?
Obviously, there would be no brick meetinghouse resembling today’s. Woodstown – whoops! – Pilesgrove Friends would be traveling to Salem for Monthly Meeting for Business and seriously considering how to replace their current [and probably inadequate] meetinghouse with something suitable for a growing membership.
