very common first name, short for Stanley. More of an older generation name. Until Eminem wrote “Stan” and it became shorthand for an obsessive fan, and a verb, to “Stan” someone. I agree Gabby wouldn’t refer to her grandfather by his first name. ETA: thinking now of generational attitudes…IMO there was a sea change a generation or two ago with regards to physicality. I’m 64. When I was a child my parents certainly hit my sister and me when we misbehaved, sometimes with a shoe. I have great parents but that was the done thing at the time. Now, it’s very different. I’ve had to call in the authorities when a student was hit by a parent (mandated reporter). It’s also cultural, because many children were from immigrant families that still adhere to corporal punishment. Therefore, someone younger may have been more likely to call 911 if they witnessed a slapping incident between a male and female. Someone older or from a foreign culture may have considered it trivial. Just speculating.
