Sunny's interpretation of the tone is another way of saying "you come here acting all superior". This is very different from accepting someone is superior, so it has the opposite effect of wanting to listen.

If someone is coming off to you as "all superior" you would only listen if you genuinely agree they are, and it's not an act. Otherwise you'll just see a person trying to make you feel inferior. Nobody listens unless they are truly convinced of that superiority, or else it's just an insult. Sunny of course chose to see this as an insult. But the opposite, taking the superiority at face value and just listening to anyone who sounds superior is no better. There are many more signals to take into consideration before deciding whether someone's opinion is worth listening to or taking into consideration.
