There are rocks directly behind Izzy’s head. Sarah takes no hesitation before she starts cackling away. I have teenagers too, and I would get out of the car and check if they’re ok. If they are fine, then sure have a laugh about it together (not post online and click bait), but to not even worry for a second that your child might have hurt themselves is really horrid. She doesn’t have a maternal bone in their body. And just because Izzy smiled straight away, that doesn’t matter either. Sometimes kids smile because they’re embarrassed or don’t want to make a fuss, in this case its probably because she knows she’s on camera. You check if they’re ok, you don’t piss yourself laughing
