“At our hostel on the eve of our return… my three travel buddies and I discussed when to schedule our shuttle… Hmmm, I said. Why don’t we make it 7:15... Always leave time for a flat tire, whispered my inner voice… When the conversation persisted, I said it out loud: “It has served me a time or two to leave time for a flat tire.” Our shuttle picked us up at 7:15 a.m.”
