It's only me pursuing something I'm not sure of

I’ve got a zillion and one things to witter on about bubbling and seething away in my brain, but they’re all very elusive. I’m doing my best, gambolling through the echoey corridors with a large butterfly net, but just when I get close to one, off it flutters again. Ooh look! There’s Political Correctness! And over there, there’s Animal Welfare being abused by Animal Rights. And right up there, look, by the skylight is a little flock of general Worries. They certainly should be caught. Where’s my stepladder?
