If you want to discuss self centered, I give you a geezer who lives at the movies, making a habit of confronting anyone who might slightly intrude on his movie experience.
He did the same thing, sans gunshot, 2 weeks earlier, even following a young woman to a restroom.
This time the lazy geezer had to ruin life for a young couple who had a rare chance to catch a movie together.
Unless he was just going to the restroom himself and she was a hysterical “me too look at me” sort of gal.
Neither group behaved properly in public. Violations on several counts of unsocial behavior.
Actions have consequences.
Saying “make me” will not generate a good result.
