My wife and I were walking to catch a boat home after work one Friday, (we lived on an island at the time). As it left later on a Friday night to accommodate shoppers, we stopped to enjoy an outdoor rock concert for about 30 mins. while we had some time. We got home an hour and a half later and learned there had been a riot just after we had left. (The Black Friday riot in Auckland for those who remember).
We told all the friends on Sunday at the meeting that we had been there and just missed the 'excitement'.
At the service meeting on Thursday, there was a local needs talk about not attending rock concerts because you'll get caught up in a riot, sure as hell.
It was given by one of the cool elders. He wasn't so cool with us after that.
