False start: Who needs money?

I don’t remember how, why, or when, but at some point, the conversation turned to debit and credit cards. I mentioned how I’d just learned our debit cards, like our American Express cards, had different numbers on them, so if I lost my card, we could report it lost and continue to use Kathryn’s, or vice versa. At this point, Kathryn announced she hadn’t brought her debit card.
