And the whole thing being started by someone starting their car and having music up loud, which is a normal parking lot occurrence! Seriously. If her kid was so scared, why isn't she comforting him? Instead, he's swinging around the posts and sign poles looking like he has not a care in the world while his mother is having an absolute fit. Shows to me that this must happen on a fairly regular basis for the kids to be so blasť about it.
Or, that he's trying to cover for being rattled.
I once saw a man in my nabe walking w/ his 4yo (maybe 5yo), and a car must have turned a corner and nearly hit them in the crosswalk (I'm guessing, I didn't see it--I only saw the argument afterward). The man was holding his son's hand and yelling, "You nearly hit my son!" He must have keyed the guy's car, because the driver was looking at the paintwork and yelling at the dad, threatening to call the cops or sue. And the dad was yelling back.
The poor little boy was standing there, still, holding his daddy's hand, and when the nasty altercation finally ended and the car drove away, the poor child collapsed in sobs.
I thought, "*You* were the one who scared your son!" If you'd modeled a calm behavior after the near-miss, he would have recovered from any fright pretty soon. Instead, you created this huge altercation that has completely undone him. He's frightened because of the nastiness -you- initiated."
She's doing a fine job of raising a couple of racist special snowflakes... (am I right that one of the kids also called him the n-word???)
So either he hears this sort of thing a lot, or he was rattled and ended up having to choose to be on his mother's side as a way to cope with it.
At the beginning, the kids don't look too invested in their mother's tirade; they look like they're trying to find ways to occupy themselves while they ignore it.
But yeah, not good for them either way, whether she's unsettled them or whether she's teaching them to be argumentative, belligerent racists.
(That woman is lucky she did that w/ someone who isn't nasty-minded back.)
(Though I wouldn't argue that the guy is a class act. A class act would have put his car in reverse and back out, then driven away, after saying to the kids (ignoring the mom), "Sorry to scare you, guys! Bye!")
