Am I really takeing this fly personally?

So your sitting on your porch, in your living room trying to relax or do paperwork, but the flies will not leave you alone. Seriously they are starting to drive you mad. Finally you get up and tear the place apart until you find a Fly swatter. You return to your former position at the ready.

But no fly comes. Do they know what awaits the next pest? Surely they cannot think logically? They they must be taunting me.
What is interesting to me is the unnoticed change in my goals. I am furious that none of the impious little pest will come. Ten minutes earlier I would be happy if thy would leave me alone. If there was something I could have held in my hand that would deter them I would have been happy. But now I am angry and they must be terminated.
