Using vacation time for a real vacation instead of an assembly.
Yes! That was a big one in my family. Even when we went on a vacation where we were not attending an assembly, my mother had to drag us all to a nearby kingdom hall while we were there, and if we were REALLY lucky, we got to go out in service while we were there.
It's like the JW''s just cannot have any enjoyment/relaxation time without feeling guilty.
