Baby forgotten at airport

See this.

These parents would be in their late twenties, I guess.

That means people their age were my pupils 12 to 15 years ago, maybe 20. I remember I used to tell them out of sheer exasperation over their habitual carelessness and irresponsibility, 'What kind of parents and teachers are you folks going to grow up into?' Remember, too, that most of these are educated and 'important' people too - doctors, engineers, lawyers, accountants, journalists - at least in their own eyes.

What should I say to the kids I handle today?
