By mistake, my wife during dinner yesterday said to your friend that we hiking the same day that we were suppose to go with them visit a city.
Uh oh, how did they react to that
They didn't say anything. I was embarrassed. I told to my wife that she was wrong about the date but my wife was insisting. She didn't notice what she was doing.
Ouch! That's too bad. I would have been cringing!
