Felony Injury to the Elderly

Man in his Sixties delivering groceries for something social to do in retirement is berated by another senior man whose delivery was late.  The two argue and the Delivery Man pushes past the Customer to leave. The customer falls and is injured. The customer turns out to be 90 years old. Attorney negotiates a misdemeanor in part because; there were no punches thrown, both men engaged in the altercation, both men were seniors.
