You’d call the police if you saw someone wearing a coat on a hot day?
“Certainly, if you see something that doesn’t look right and by that, I mean someone dressed in a heavy winter coat on a hot, sunny day and not a child with messy hair.”
I have seen that sort of thing in many a movie with no explanation. One that comes to mind is a chick flick called Phenomenon that I went to see to please my dear wife. I asked her why John Travolta was sitting in the front room of a house with a field of mature corn clearly visible through a SCREEN door, the main door standing open but Travolta was wearing a heavy leather jacket. I see such things all the time and it is one reason I never go to a movie theater any longer.
