This is nerve-racking

since I don't know what I must pretend to know.

Therefore I pretend to know everything.
 
 

I feel you know what I'm supposed to know

but you can't tell me what it is

because you don't know

that I don't know what it is.
 
 

You may know what I don't know,

but not that I don't know it,

and I can't tell you.

So you will

have to

tell me
