Harvard mom has a condescending attitude throughout the video but what was her attitude prior to the video being recorded? If Harvard mom comes out making demands in a abrasive manner, I could see sidewalk mom or anyone else for that matter likely digging in their heels. I can also see Harvard mom doing an attitude 180 when the camera comes out.
I have a hard time believing that a mother of an infant would be difficult when another mother calmly and politely informs that she's trying to get her kids down for a nap. Something tells me that the initial request was not calm nor polite.
A lot of mothers are just insane about defending their children’s behavior these days. It’s entirely possible that if the Harvard mom had said to the sidewalk mom (*snicker*), “Excuse me, ma’am. My children are taking a nap right there ... *point to window*. Could you please help your daughter keep her volume down while she’s playing? Thank you,” the sidewalk mom would have gone ballistic.
