When I was attending my local KH, they had no second school due to the low numbers. The elders were also having to constantly cover parts for the ministry school, as it was called then.
I could never get my head round the low turnout, especially when they merged the two congregations together...Now I know why, most active JW's probably think it is a crock of shit!
The last memorial I went to was actually pretty shocking in the way of numbers. They always needed to use the second school and back room. The last one I attended never even got this close!
