While being surrounded by strangers struggling with their problems at a public place, say,
in a lift,
in a waiting room,
in a queue at the bank, cinema,
or
elsewhere,

Actually, behavioural matters spread faster than we think.

Wabi-Sabi is a Japanese philosophy that celebrates-respects "age" and the imperfections created by ageing (usually in inanimate objects like vases, wooden benches, etc.).
