You are a placeholder.
You satisfy the barest of needs; you are incomplete.
You are blunt and static; you take no argument.
You are vague and opaque; you offer no comment.
You are private and isolated; you are inaccessible.
I get nothing in return; you are void.

And yet

You can still be expanded, recast, redefined; you are abstract.
You are beautiful and inviting; you are composed.
You are self-aware and internal; you are reflective.
You are permissive and graceful; you are exceptional.
You hold the promise of things not foreseen; you are hinting.
You are in a place, held.
