What respect means to me is not to have the best realtionship with the person but to be able to talk or work together without being negative to each other.
One time I went to a parent teachers conference and I had sweatpants on and a graphic t-shirt with satan playing with cats on it. While my parents were talkng to the teacher, I interrupted and said, “I like your sneakers”. I think I may have cross the bounday and was too Informal.
