@ButtWorldsMan I have had this experience, usually with women. The problem word is "if". Their brain can't process a conditional statement, so they think "if" is just filler, like "um". They just hear you say the condition and the consequence one after another, as factual claims.
@Mongoliaboo @ButtWorldsMan
Women can definitely process conditional statements and are very good at it. The difference is you believe she's thinking about the content of the discussion while in reality she's testing different words to see which one will make you give her what she wants.
Next time pay attention to the outcome of the "argument" instead of the actual content. If her standing got higher or she received something from you for free just reciting random words, she won.
