Why Do We Sometimes Say the Opposite of What We Mean?

Sometimes, we say the opposite of what we mean because our brains are confused or overwhelmed. Imagine you're very tired and someone asks you a question. Instead of saying you're tired, your brain says something like 'I'm fine!' just to hide how exhausted you really feel.

When people get nervous or excited, their brain can make mistakes in processing what they want to say. This is called paralanguage, like when you say one thing but your tone of voice shows the opposite.

Sometimes, if we take a deep breath before speaking, we can remember what we really mean and say it properly.
