I finally understand why people put those festive ‘Baby On Board’ signs in their car windows. It’s not for the certain je ne sais quois it adds to your people mover, as elegant as they are. It’s not to boast about your ability to reproduce (that’s what the “My Family” stickers are for).
It is, I’ve realised, to warn people.
It’s a yellow diamond of distress. SHIT DRIVER INSIDE.
