Have you ever been locked in a (afterwards silly) thought and acted on it without thinking further? Spoiler: Example I saw something wrong (thought the traffic light for pedestrians on one side of the road was green while the traffic light for the cars going through there was also green) and immediatly told a policewoman who was right beside me that the traffic lights weren't working... Didn't take even one second to check, but I just up and went. There was a small stripe in the middle of the road, separating both sides, where pedestrians could wait. I didn't see the TL on my side, where it was red for pedestrians. What is your embarrassing story?
