I held the door for her
One manner I learned as a young boy was “Ladies first.” A gentleman always opens the door for a lady, and follows her in. When my family went out for dinner, I always opened the door for my mother. This was the 1960s.
In college one weekend night I had a date for a movie. After the movie, my date and I went to a local deli for dessert. As we approached the deli entrance, I held the door for her. She looked at me askance, as if to say, “What are you doing?” This was 1970 or 71.
Times do change.
