In an attempt to help people along, to share ideas there comes a time when we s tihould recognize who we are talking with and adjust our tone, topic, goal...exit strategy. Some are in conversations only to repeat what they have previously heard while others are seeking to understand, to increase in knowledge.
How do you exit when you discover that your partner in the conversation is only repeating...not listening...not sharing? Do you have a 'go to' exit? "I gotta go check my food on the stove?" or "dang prostate! I gotta go!" or "Musta been a bad burrito, excuse me?"
Staying in the conversation beyond your exit is a fools errand. Don't be mislead by thinking this one extra phrase or idea will get them to at least hear you- a fools errand. Remember: when they tell you who they are, believe them!
