The thing is, nobody actually ever hears what you intend them to hear… Ever. They all hear something different. Perhaps not always as extreme of a difference, but if I say dog I think of a certain type of dog, and you think of a different type of dog. Even something like the color red is seen differently by every person to a slight degree. Something as simple as “lets meet at 1pm” will be generally understood as to it’s intent, but it will take each person a different amount of time to arrive at 1pm since time is relative to the person who experiences it.
When you try to convey your thoughts to another person the best you can hope for is that they like you so that they will interpret your words into a pleasant translation.
