About scared me to death

As usual, I'm a day late in reporting on this, but the other night I thought I was going to have a heart attack. I was out in the backyard in the lawn swing with my headphones on, enjoying being by myself and just musing over a lot of things, when BOOM out of nowhere this guy comes up our alley and he's at the halfway point before I even see him; so from my view it's just like he came out of nowhere and this guy was only wearing jeans and his shoes, and just walked on by...if I may, if you go to the 9:54 mark on this video, that's exactly what it was like seeing that:




Anybody else have a moment like this where something just comes out of nowhere and you about hit the ceiling?

I'm usually the one who scares the shit out of others. I didn't think I was that hideous.
