-One more thing....we are usually told to lock our pets away while he blesses the house.
A small but quite important point. It doesn't take much imagination to work out what a cat's reaction to being sprayed by a horsehair brush soaked in holy water will be ....
I always blessed every animal in the house whenever doing this. No animal ever ran away; most walked up to me and just stared at me. The owners of the home were ususally more skittish than the animals!
My favorites were always when kids were in the house! They were always such willing helpers, holding my books or incense or candles, and pointing out their bikes or other possessions of theirs. The kids often 'got it' better than the adults; maybe this is because kids understand how threatening the world can be and therefore we need help while adults fool ourselves into thinking we canhandle everything alone.
If I may make a suggestion: the priest should never be alone. Once I was lost and called ahead to let the owners know that I would be delayed, maybe 15 minutes. The lady of the house said that would be fine.
When I showed up, the lady was wearing only a towel. Her husband was not in the house, and she said she had just come out of the shower....but her hair was completely dry. She did say that the family icons were all ready for me...in the bedroom.
I left, saying that an emergency had come up. The next time I was there I verified that her husband would be present, and I brought a companion of my own just in case.
Weird things happen out there, so never let the priest be alone with any person, please!
