There was a recent case in Pahrump, Nevada where a man didn’t like his daughter’s choice of boyfriends. Man told 21 year old male to leave his property, young man refused, continued sitting in his car in the driveway, father shot him dead.
Wow - totally wrong of course. The ‘get off the lawn’ thing is from FARK. I love reading FARK when some old person does something and the cut line is ‘and get off the lawn’.
