Yes, I realize that this incident took you completely by surprise and it would have been hard to pretend you had not seen the woman, especially when you must have practically tripped on her. However, I guess I was speaking figuratively when I said, ‘Don’t look, don’t see.’ To me, in this case, ‘custody of the eyes’ means more like ‘don’t see what you are not meant to see.’ Hard to do in this case, I agree, but something to keep in mind for these instances in the future, so the other person could ‘save face.’
I’m sure someone posted a while back about just such an incident; someone had seen a woman in a compromising position, she knew she had been seen, yet he continued as though he had not seen her. He said that later in the day he met up with the woman along the route and they ended up having a wonderful discussion about something or the other, as though the previous incident had never occurred. That sure beats the awful scowl you said you got.
