One time I was in a trance going to work, very very tired. Being I work third shift there is nobody on the road at 11:30 at night. I came up to a red light where there were parallel parked cars on both sides.
I had forgotten I put my head unit on pause because of my cell phone ringing earlier, so I took it off pause, still kind of dazed out. The radio wasn't *that* loud, it wasn't anything crazy loud. But I set off a car alarm directly next to me that was screaming loud. I almost wet my pants in my very own car that instant. It was the least I expected at that time. Now when I take my head unit off of pause I always think twice.
