My H has a tendency to do this - flouncing out of restaurants and leaving me sitting there on my own being stared at, getting upset and raising his voice in the middle of the street as we're walking along. Countless examples, sometimes several times a week, sometimes it doesn't happen for months.
Why do people do this? Is it that he just doesn't have a sense of self consciousness? Or is it because he knows I will try to calm things down?
