I fear (pun intended) that I've developed some form of spheksophobia (fear of wasps). Wasps, bees and bumblebees didn't used to bother me, but sometime within the past two years I've started to fear them. I have never been stung or bitten by anything worse than a horse-fly, so I really have no idea what caused it.
Now whenever I see a yellow-and-black insect, I get scared and usually stop all movement. Even if the insect is nowhere near me, and/or heading the opposite way.
Once I had my window open, and a wasp flew in (I didn't have a mosquito net on the window). I couldn't bring myself to enter the room until the damn thing flew away. And that took over an hour.
Yet another reason why winter is my favourite season.
