It’s just a jar filled with what?

I don’t know what should be filled in, no, I don’t.

Maybe the part missed a long time ago.

How can the missing part fill it when it’s missing?

It’s supposed to be a full jar of what?

I should be the filling stuffed it all.

But I am completely lost.

How can I fill the jar when I am the lost filling?

I’m just a jar without colour.
