My pen is………..
Is my pen…
Where is my pen?
Your pen is…
It is somewhere.
It is where I can’t see.
Someone takes it.
It is taken.
I don’t know where it is.
I wonder where it is.
Noone knows where it is.
I want to know where it is.
Can you tell me where it is?
There’s a pen somewhere but I don’t know if it’s mine.
There’s a pen somewhere but I don’t know if it’s yours.
It’s hard to find where it is.
Where it is is hard to find.
No matter where it is, I don’t mention it.
I go find it no matter where it is.
