An eight year-old is hardy an infant. Kids aren’t going to die in 5 or 10 minutes. The author obviously has Samaritans confused with Pharisees.
Never, ever talk to the police.
you don’t know. you could fall and be knocked unconscious. you could be abducted, or the child could. we have plenty of carjackings with infants in the car whilst mom/dad ran inside to pay for gas. not sure i would go so far as call the police, but i certainly wouldn’t leave my kid (and i never did) in teh car alone
