What should I say? I'll answer yours?

Good Lord, when did Facebook become some sort of legal site for recognizing relationships?

Here's a clue, Tootsie. Facebook is a marketing tool, not reality.

But if you must write something, just say, "X and I are very close, in ways that can't be put into words." If anybody asks what you mean by that (though I can't imagine anyone caring enough to bother), tell them to mind their own business.
