Do you or do you not agree that the reason we put numerous restrictions on driving is to reduce the likelihood and occurrence of accidents, injuries and deaths associated with driving? Yes or no?
I'm sure you've encountered this frequently on RF. You ask a question, don't get an answer, ask again, are ignored again, and it goes on without resolution for as long as one allows it. You're left to wonder if they are unable to see and understand question marks, if they forgot the question was there (every time) between reading the question and answering it, if they're maliciously trolling you, if they realize that their position is indefensible but can't admit as much, or maybe something else I haven't thought of, but it really doesn't matter which it is, and none of it is acceptable. I can imagine dealing with each of these types in succession and it wouldn't matter which was which. Which are you dealing with now? Who knows? And like I said, it doesn't matter.
Still, there's a tendency for us all to TRY to get cooperation in the assumption that this other person would if they could, and it's just a matter of finding the right words to get through. But we see that's rarely if ever the case. When does the other guy say on the fourth or fifth try that he suddenly understands and provides a responsive reply? Never for me.
So, I modified my approach. I put an end to it after one or at most two asks by answering the question for the other guy. In this case, I would just say that I believe his answer yes, offer him a chance to disagree if he does, let him know that his silence is deemed tacit agreement, and move forward. Why put yourself through this?
