I heart New York

Today on my way to work, I walked past a gaggle of tourists taking photos of the UN building. This is a pretty common occurrence, and I wouldn't have noticed it had I not overheard this conversation:

Small boy: "Daddy, who are all those people and why are they taking so many pictures?"

Father: "They're tourists."

Small boy: "What's tourists?"

Father: "They're people who don't live in New York."

Small boy (visibly perplexed): "But why don't they live in New York?"

Good bloody question, I say.
