Idioms and Phrases with goldfish bowl
A situation affording no privacy, as in Being in a goldfish bowl comes with the senator's job—there's no avoiding it. The glass bowl allowing one to view goldfish from every direction was transferred first, in the 1920s, to a police interrogation room equipped with a one-way mirror. By the mid-1900s the expression was being used more broadly.
