No, not fear of small things. Small fears of things.
What are those things that make you squirm, vaguely uncomfortable, or just wish you were elsewhere?
I’ve got two. Needles, not just any needles, but hypodermic ones. They make me cross my arms to protect my elbows.
The other is wasps. The way they fly slow enough for you to track and see them coming, but fast enough to keep you on guard. The characteristic buzzing note. The fact that they just don’t die (I cut one in half and left it for dead while defending myself with a flyswatter. The next day, both parts were still squirming around at the bottom of the trashcan.) They’re ugly little terminator insects.
