It depends, I don't or try not to argue or debate on line. I don't see the point. I'm not saying I never have, but 99% of the time you're not going to change someone's mind.
Arguing with my Husband just happens sometimes. I've apologized and so has he. There's been a few times we've agreed to disagree. We don't always view kid's bad behavior consequences the same way, but now that we've reached the age of electronics and WI FI, punishment decisions are much easier.
When it it comes to my kid's I don't argue. They're 10 and 11, I do listen when they don't think something is fair, but they're arguments usually involve not wanting to take a shower or brush their teeth, they lose.
