That only happens in the movies.
In real life fighting over small stuff just means you spend a lot of time fighting.
These couples need to meet somewhere in the middle.
One couple I know...she's got a nice voice but she goes on and on and on...
Her husband sighs and NEVER has anything of substance to say. My take on it is that she's desperate to get some leadership from him on issues and thinks that by constantly engaging him it will happen. I think if he gave his perspective on things she would talk less. Who knows? Maybe this is true in general.
