I like the irony of the title... that she was never in your house, but her loss enters your house so tangibly. "A loss has come." I couldn't help smiling at the cleverness of those four words.
As for the whole poem, I love your use of repetition, especially how you altered each line just enough to make it distinct, and still stick with the theme. The result is a flowing, light and easy read, appropriate to one whose underlying sentiments are the focus of the poem.
It is a sad situation. Loss of that not tangible can itself be tangible. I've felt this myself, so at least a little, I understand...
Lovely tribute, Ron. And of course I'm voting.
"Faith" means the will to avoid knowing what is true.
