When is it proper to say "excuse me"?
Today, someone said it to me in a store. We were walking towards each other, no where near a collision, and an "excuse me" came out of their mouth. Was I supposed to do something??? I froze.
Although Europeans stand too close, push and shove, it is an equal opportunity playing field. Last week in Munich, I walked the back of a shoe off of someone's foot at the train station. I didn't say excuse me, or sorry, I just kept walking. The person just fixed their shoe, didn't even know who did it, didn't scowl and went on stepping on other people's heels. So excuse me if I prefer it that way.
