What disappears the moment you say its name?
Common Wrong Answers
“Sound”
Sound does not disappear when you say its name; in fact, saying the word 'sound' creates sound itself.
“A secret”
While a secret may lose its secrecy when spoken, it doesn't disappear outright; it still exists even after being shared.
“Time”
Time continues to flow regardless of whether you mention it or not; it does not vanish upon being named.
