”We’ve been living in a lethal fantasy, Hébert realized. We’ve lulled ourselves into believing that in an emergency, someone else will always come along to rescue us.

Which was strange, because until recently you weren’t an adult until you could rescue someone. Rites of passage for most cultures were based on sheer physical usefulness: you counted as a person only when you showed you could be counted on.”
