Another Riddle

The answer is " silence"

There must be a standard answer to this but I would like to point out that the word "Burglar" can be like this. If you see a burglar inthe house, and shout burglar then he will disappear. But when you shout "Silence" you can see the silence in front of you. Silence disappears only when there is noise.

khyuga thats what you are. is that the answer. greetings. : )

not sure
