We were boating -- in his power boat -- not yet married so both of us were trying to be especially 'diplomatic' and 'courteous' to each other. I was in a leg cast from a broken ankle which put me in a not-best physical condition and it definitely slowed my movements down a lot but I WAS making an effort to stay in good humor, despite discomfort.
I had spent over 20 years as a pleasure sailor (sailboats), confidently knowledgeable, while 'that man' was a power boater (they are called stink potters), and it seemed to me that it was a male characteristic to imply they are more knowledgeable than members of the other gender. We did each have a different approach to water crafts but again, were both trying to avoid opportunity for disagreement.
We motored into the slip and I began to tie the boat to the dock cleats, using proper knots and technique, but knowing he was closely watching me. I was feeling very insecure with him watching.
As I was carefully and skillfully tying his boat to the dock, I heard him say "You're not so great!" ... huh? HUH!!! He said I wasn't so great???? and he expects I'm going to marry him, that good for nothing so and so ... and that's when the fight began!About 3 days later, he explained ... what he said was "Your knots are great!"
It's funny now and a good lesson! Wasn't funny at the time.
