A 180 is doing something that is the complete opposite of what you would normally do.
And it doesn't have to be complaint related (because if you do it simply because your spouse complained, then you are being manipulative).
180 is about listening to the complaints, seeing if they fall in line with what you want for yourself AND it is also about looking at yourself and making changes in areas where you want to be different.
So I would be more curious to ask...
Was there a complaint about you being to stuffy or something? Were you just trying to relax and have fun? What exactly was behind the behavior?
