Ok.. is this woman a moron?
if someone throws a rock/brick/concrete-block at your car... you DO NOT STOP. You DO NOT confront the attacker. Your concern should be to get the kids and yourself away from harm. The threat may not be over. The longer you stay in the area, the higher the odds of a follow-on event.
Get your vehicle and kids out of the area asap and report it to the cops.
she is lucky they didn't carjack her... or worse
Lawn Guyland women have their brains fried from to many trips to Guido McSchwartz's hair salon and spa on Sunrise Highway.
Not necessarily, IMO. The shock and rage she experienced probably triggered her action. Maybe it could be rightfully called temporary insanity!
Nevertheless, your advice to get away asap makes perfect sense. Report it to police pronto and seethe later.
