That is funny Chris.
I keep imagining the number of folks that look at us and think the same thing and I think they're a bunch of complacent dummies...
A tad of an over-reaction, but at least they were thinking along the right lines of being prepared and not waiting on someone else to take care of things.
A friendly reminder about the sprinkler system would be the civil thing to do, sounds like they are at least teachable to some extent...
Besides, one never knows, you may be in need of their help at some point....
