“What was even the need for this convention?”

So we went for the first convention of the year yesterday, and when we close I hear this super PIMI older woman grumbling. “What was the need for this convention anyway? It's the same thing we learn at the kingdom hall.” I was flabbergasted. Before, you would hear everyone saying 'this is the best convention yet', but within the last three conventions(from last year), I haven't heard anyone say that. Are even those in deep getting tired as well?
