Depends. If I get the feeling that result is the same no matter what or how I do it, then yes, I'll throw in the towel and do something else as I usually don't want to waste my time on futile attempts. IMO it's the only sensible thing to do in such circumstances as I have witnessed relationships where everything seems to be based on finding errors from things the other one does and bemoaning them as if they were the most important things in the world. I try to do my best not doing it with my wife, son and daughter, as I want to encourage them to try out things by themselves and offer guidance when they need it rather than wait for them to fail so I can ridicule and belittle them. "It's you fault and your fault only!11!" IMO is as nonconstructive as "it's all the other's fault!11!!" as they both concentrate on finding someone guilty instead of analyzing why and how certain things happened. I'm sorry, but I don't like the blame games, hence my little bit cynical remark.
