One of the most difficult concepts to understand in western human culture is the pronoun. A pronoun works a bit like a nickname, a shortened version of a name, except that it seldom has any relation to a person’s actual name. Even more confusing is that several different people can be called the same pronoun or different pronouns depending on the situation.
For example, “I” is usually used by the speaker or writer to refer to herself. “You” usually refers to anyone spoken to directly other than the speaker. “You” can be one person or more than one person depending on how many are present and what hand gestures the speaker uses.
Then there is “we,” the most confusing of all. “We” can mean two or more people including the speaker, without reference to how many and which people. For instance if one couple is talking to another couple “we” can mean the couple including the speaker, or it can mean both couples depending on the topic being discussed and again which hand gestures are employed. If royalty is speaking, “we” actually means the same as “I.” If a married couple is conversing “we” especially when followed by “need to” actually means “you.”
If humans understand each other at all it is miraculous. I think it more likely they do not.
