Only things that come to mind:
• One time when my grandma and I were going to work in downtown Seattle, I turned right on a one-way street - in the wrong direction.... embarassing for me though since I claim to know the streets in downtown, guess I just forgot, luckily there was alley nearby for me to turn before any police saw.
• at McDonald's, when I had to use the restroom and I went into the female restroom instead of the male restroom, I was embarrassed when getting out and in front of me was the sign for the male restroom, looked behind me and yep, it the was the female restroom, a working employee did see me and just laughed.... I have not been to that McDonald's since, still embarrassed.
