One day I was walking across the Morrison Bridge to my job (having taken the MAX to the Yamhill Station). After reaching the three-quarters mark, I found myself with the desire to dash into traffic.

Indeed, this strange desire kept growing stronger and stronger! Much to my chagrine, I had to keep my eyes on the sidewalk, and even lean towards the railing, to resist an almost physical urging. I kept thinking, "I could make it if I sprinted." To which I responded, naturally enough, "Hell no, you idiot! You'll die instantly."

Obviously enough, I made it across without flinging myself to certain death. Even so, it was a chilling experience.
