I'm not sure if this is related or not, but I've often heard people say they went to a particular stream and "Nothing was happening."
I used to assume that meant they went there and fished, trying all the standard nymph patterns, maybe some streamers, going through their fly boxes, trying everything, and not being able to catch anything despite all these efforts.
But it could mean that they went there, stood on the bank looking out over the water and didn't see any trout rising. Said "Nothing is happening." Then got back in the vehicle and drove away.
