What do you do with all the hymns you still sing in the shower?

I haven't been to church in four years. I don't miss Sundays. I don't miss the politics. I don't miss pretending.

But this morning I was making coffee and I caught myself humming Be Thou My Vision and it undid me for twenty minutes.

I'm asking without a theological frame: what do you do with the good things the old house gave you, after you've left it?
