Good question. For me the answer depends on what we are talking about. If it has to do with morals and ethics and things like that, NO I will not change my mind! Now, if we are talking about something less serious, sure I can change my mind if the argument is a reasonable one and is plausible. I'm very stubborn when it comes to ethic, morals and politics. If you're trying to change my mind on those issues, you may as well forget it!
At work it is my way because it is my responsibility and I am the on that needs to answer for it. I will listen to other points of view but I make the final call. At home it is very different. My wife and I try to work as a team and make team decisions. The kids are older and don't listen to us anymore unless they need something. Then they ask or advice.
I have to make quick decisions. No way to second guess, so once its been made, its not changing.But, if its during a discussion where we both have some good knowledge on the subject, I can change my mind later, if I find after research that they're actually right,then let them know later over a beer. Guys have egos.Always present to some degree.
