Imagine you are driving to a dinner party with your wife. You are running late. You are both irritated with the other. You both believe the other is the cause for being late. You are bickering on the drive over. Your partner gets frustrated and picks up their cellphone and says s/he is going to call the host and cancel. You grab the cellphone to prevent her from doing so. She yells at you to give it back and starts punching you in the arm. You put your hand out to stop her from hitting you because you are driving. In anger you say that she'd better stop hitting you or she'll regret it. She gets even more upset and demands you pull over and let her out. You are concerned for her safety of dropping her on the side of the road at night and decided to find a parking lot to pull into some distance down the road to try and talk and calm things down.
