Take the best and most convenient way

I don't see why some people can't give others some information despite them being not confidential. Even if we annoy them till they can't take it. Obviously, those are dumb.
This ways help to hide information:
1) Give an incorrect answer that is not obviously incorrect.
2) Ignore the other person( It doesn't work all the time though )
Why NO.2 does not work 100%? You can still get annoyed. Why? Go watch the Spongebob episode when Patrick went to boating school with Spongebob. If you still don't understand, go tag in the tagboard. Just take life the easy way. A prankster knows when to take things seriously and when he can don't. Life is complicate enough, don't make it worse. I don't see why an idiot knows that but the smart ones don't. There is something called logic. Know it well and you'll do things more efficiently.
