Do you consider yourself a "jumpy" person?
Although I like to think of myself as a tough guy (I'm not at all), I'm often startled by non-threatening things. Take this picture, for example.
Last week, I was walking on a nearby trail when I saw a snake crawling towards me. I was reading a book on my phone, which I love to do while walking, and I saw the creature coming from my left. I jumped and moved over into the woods to make sure I could see what type of snake it was before running for my life. It was a...spraypaint snake.
In other words, it wasn't a snake at all -- just a poorly drawn S or 5 on the trail.
What have you jumped at that turned out to be something non-threatening?
