Buzzing around achieving nothing

I've been increasingly irritated by a housefly for the last couple of days. It's wasting it's energy and its short lifespan, buzzing around in every direction, accomplish nothing and generally causing a nuisance. Unlike a spider, you can't help it. With a spider you can put a glass over it and chuck it out the window in the hope that it might at least take a risk and live a useful life. And there is a perfect Ukip metaphor. Here we have an entity that largely feeds upon faeces and regurgitates it, buzzing around unproductively, annoying people, and using up energy without achieving anything.

You might want to help it but it never stays in one place long enough to capture it. You can open all the windows, causing yourself some discomfort, you can even waft it in the right direction, but it still won't go in the right direction. In the end you just have to resign yourself to the fact that it will just continue to cause an irritation, will continue consuming shit, and waste its energy producing nothing in a short and pointless life.
