Do insane people know that they are insane?

They find out and forget over and over.

Yes I do

Depends if they think what they are doing is normal when everyone else thinks its not normal

the sane person thinks he is insane, while the insane person thinks he is sane

Apparently all you have to do is admit it and no one believes you.

Nope. That would be too rational of them.

Sure we do!!

some of them :)

Are you insane

yes, i do
