The author attends a party hosted by their homestay brother in London, where they meet and talk with several of the guests. In conversing with a medical student, Luke, the author learns that medical school in the UK costs less than $50,000 total, much cheaper than in the US. Luke is surprised to hear how much more American undergraduate education costs. Later, when the author wonders why more Americans don't study abroad, Luke jokes that most Americans don't even have passports. Research shows only 36% of Americans hold valid passports, far fewer than the over 80% of UK citizens with passports. The conversation was an eye-opening experience that highlighted differences between Americans and the English.
