atleast teach children some basic social skills

if in a children's school, a teacher showed a political debate on a tv in the classroom 

and when the politicians started arguing, the teacher would pull out a handheld gaming device, like a gameboy or mobile phone and start playing while saying: "just a game" 

that would increase childrens understanding of how things work 

at home while two parents are arguing, an older sibling pulled out a handheld gaming device like gameboy or mobile phone and started playing while saying: "just a game" 

that would increase childrens understanding of how things work
