Two dumb things.
At the neighborhood Trader Joe's, I saw a guy kind of gliding along down the aisle. When I looked more closely, I saw that he was riding his skateboard. Indoors. In a grocery store. He had that blank look indicating that perhaps the thought had never occured to him that nobody rides skateboards in grocery stores. He wasn't some rebel who realized that he was doing something wrong and didn't care -- which you could almost respect. He was just a thoughtless schmuck. Occasionally, he would step off his skateboard and wander away from it, just leaving it in the aisle as he stared, slack-jawed with his teeth in his mouth, at the frozen foods.
So, fortified with what I though was my daily dose of stupidity, I went on my merry way.
An hour or so later, as I crossed Burnside at NW 23rd, I saw a skateboarder who made the first guy look like a complete brainiac. My new hero came zipping down the hill in the left hand lane! He swerved there from the right hand lane to avoid a stopping bus! Oh, it gets better. He reached the intersection, and he rode through it swerving over into the oncoming lanes and then the sidewalk!
