I've just watched a documentary called "Herb and Dorothy". I enjoyed it. It's really liberating to see the people who live like this.
The film also reminded me the time I visited Sir John Soane's house and museum. It was a place where I could visually feel the power of one's obsession. Very liberating experience.
A local person gave me a city tour. In addition to the must-see famous spots, she shared her own hangouts. Her schools, favorite sushi place, supermarkets, places to buy sweets.. I enjoyed it so much. That's what I always want to know when I visit someone's hometown.
