Democrats, have you ever had a profitable conversation with a Republican where you found common ground? If so, what was the experience?" ?

I'm curious if any Democrats ever had a constructive conversation with Republicans that produced good fruits? If so, how often does it happen? Almost every conversation I have with Republicans ends the same way: Toxicity, finger-pointing, and no common ground; Republicans I've met have no room for any view outside their own. 

With all the political debate, everyone is firm in their own viewpoints and won't change; it's pointless to discuss when there is no progress. Why even have conversations with Republicans outside of understanding them, which, at times, I wish I didn't. 

The perpetual disagreements accomplish nothing, so why do people continue to think they do like a mouse caught in a maze? Am I wrong? Do other Democrats have friendly conversations that lead somewhere?
