Some couples play board games, we have "toothpaste chicken": a high-stakes game of nerves where we squeeze the last remaining dabs of paste out of the tube until one of us caves and buys another.
But lo and behold, here, perched on the edge of the sink, all plump and pretty, is a brand new tube of toothpaste that I didn't buy.
"Remember that time we both bought toothpaste on the same day?" Katie says by way of explanation. "I was looking for a travel sized tube just now and I kept picking that one up and putting it aside," indicating the new tube, "not even seeing it as toothpaste."
