People are always impressed by how formal and informal tone and relative status is encoded in East Asian languages and how English doesn't have this and is supposedly egalitarian. Here's an example to show how it does exist also in English! Social relations are going to be expressed somehow. It's just how human culture works. The lower status person typically uses longer, more elaborate phrasing, while the higher status person blurts shorter ones. I wouldn't be surprised if equivalents exist in animals too.
