I’m withholding judgment until I find out exactly what the argument was about. Perhaps the punch was appropriate.

Ann Arbor police Lt. Renee Bush said the man went to a party at a home in the 100 block of North Ingalls Street at about 2 p.m. on Saturday. Bush said the man was sitting on the porch with some people he had just met, talking about books and authors.
The 34-year-old man was then approached by another party guest, who started speaking to him in a condescending manner. An argument ensued and the man was suddenly struck in the side of the head, suffering a cut to his left ear, Bush said.
