Arguing is key, but you have to know how to argue whether it's your kids or your spouse. As hokey as it sounds, active listening works wonders with both. This is where your kid/spouse shouts/says something to you and the first thing you do is bite your tongue...then say back to them "what I hear you saying is..." and then summarize what you think they are expressing. You might be wrong, in which case they will correct your interpretation, or you might be right, in which case they feel "heard" and amazing things happen. I've tried to teach the technique to the kids' Mom, but she thinks "it's all bullshit" and wants to play the "did too/did not" game with them like she's a third-grader. After getting in fights and calling her daughter a "fucking little bitch" she was shocked - shocked I tell you - to hear her daughter call her that right back at the age of 9.
In many ways she's the most immature.
Anyways, definite yes on arguments.
