I used to do this too, someone pointed it out to me. I said, "I'm sorry," way too much.
The other day I was going to a thrift store that happens to be right next door to an Alano Club (AA). As I walked toward the door of the thrift store a beautiful 20 something girl with a cup of coffee was walking toward me on the sidewalk. We had to switch sides to go into our doors, and she said, "I'm sorry," twice - just for walking on the sidewalk and entering an AA meeting. It was so sad, I wanted to hug her.
I didn't. That's what AA is for
