Assuming I am upper class and not upper-middle, my experiences that feel most representative are the restaurant outings. There would be a large group of "successful" people in their 40s to 70s. There would typically be a few of their late 20s children and then my sister and I would be the youngest by 10-20 years. The general feeling from the people was one of respect. I would be this 10 year old kid having these "successful" people include me in conversation and treat me as an equal. I was taught that I am not inferior to anybody. My interactions with authority figures at school and otherwise are heavily based on this. I am an introvert but in such situations I become very outgoing, whereas most people my age seem to do the reverse.
