Who Art In…?

Yesterday, we got to meet the hospital chaplain, maybe. Conservatively dressed, heels a little too high, eyes reassuringly thousand yard starey. Very nice. She then pitched us all doing the Our Father together. Bugger. That one's been a while. Just how lapsed am I? No worries.
I was bought up Irish Catholic, and like an old Status Quo tune, you start it, I'll remember all the words. Turns out, nobody knew exactly who she worked for. The first thing that crossed my mind was,
"She's been thrown out of here three times today already!"
Now I think she was a Gideon Ninja. Appears from nowhere, does the nice, vanishes...
