LOL! Great question!
1) When I was really little, I couldn't get a bottle of water open. Naturally, using a knife to pry to cap off seemed like a good idea. It wasn't. Long story short, I came within an inch or so of stabbing myself in the eye.
2) I was driving on a divided interstate (two lanes either direction). I was passing a semi on the left. Half-way in, the semi driver decided to switch lanes and almost ran me off the road into a ditch. Thank God for horns.
3) Sometimes I get what I call "road hypnosis". I'll start at point A, and arrive at point B not recalling anything about the journey between. Yeah. Once I was in my driveway, and suddenly I was pulling into the lot at work--had no clue what had happened in between. I get it bad on interstates, too. Sometimes I'll look at the clock and it's like 5 minutes pass in the span of a couple seconds. Scary to think what could happen in one of the "gaps".
