Polite vs Impolite

I think something common with human behavior is that people change their attitude based on the person they are interacting with. A highly respected individual would receive more respect than just a random person. An example of this is a doctor. A doctor gets the title "Dr." behind their name (everyone else just has "Mr." or "Ms." or "Mrs."), and they are addressed this way, in respect, and have a high status in society. Due to their elite status, people are usually polite to them because they feel inferior to the doctor. But there are also other situations where the need to use polite or impolite language changes. Adding on to the examples of respected individuals, people tend to be more nice and polite to people who are older than them, like their teachers, bosses, and even their parents and grandparents. Other than just being polite, if there's someone who's superior to you, you feel the pressure to impress them. For example, if you're playing a sport, you'll play the best you can to make your parents and your coach proud. In contrast, when you are around people you've known for a long time, like your friends, you don't tend to be so nice. From what I've seen, people don't restrict themselves when they are around their friends, and they say whatever they want to say. This creates an impolite atmosphere where one friend teases another friend because they know they'll get laughs from it. But this doesn't ruin friendships or create much drama because both parties know it's a joke and they have fun. But if you are meeting someone new for the first time, even if it's someone your age or younger, you tend to be polite to them because you want to create a good impression, and if you start off by making them mad or being rude, then you won't have a good relationship with that person at all.
