Our reading
An editorial interpretation.
The advice describes children through the unusually formal phrase anyone to whom you have given birth. That roundabout wording makes an ordinary parental relationship sound like a special category of borrower. The joke turns reluctance to lend a car into a sweeping and sharply phrased household rule.
