There was a lot of this in the neighborhood I grew up in---as a kid, I remember looking out the window early one morning to see a parent (George) chasing his very young (under 10 for sure...) son with a two by four---George finally went away when he broke all the windows in the house with his family inside...(George was a police officer...)
Some Sundays, parents would fight in the street, it would begin with "your kid...." vs "no, YOUR KID...."---sometimes someone would turn a garden hose on the fight
My parents did not participate in this (nor our neighbors to left or right--a few others) but it was "normal" for the street...
Years later, I had really forgotten this....or, when I thought about it it didn't arouse much emotion, a laugh at the absurdity...
Then, I was in a friend's apartment when I heard the fight across the street--He had come home in the AM, She was waiting up, the screaming began, ....took a typical course of rising accusations and slamming doors----I felt very disturbed and shaken.
And then realized that is was something I was once inured to---and began to wonder what effect this must have had on me when I was young
I had previously thought only of my friends/&other kids who had to live in those houses....now, I realize it affected us all. (and I think my parents failure to talk about this, or anything else unpleasant, added to the damage...)
I have since witnessed a few street fights etc. ---- sorry, just a ramble after all
oh, and the feeling of panic when another neighbor (Mrs. Gooden) accused me of slashing a car tire, as I happened to be walking by when she discovered this---her screaming at me as I hurried home, wondering if my parents could Acutally Believe I would do such a crazy thing....
