Being a hermit is not always easy. There is the true, spiritually nourishing, story of St Honoratus, who went to the Îles de Lérins off Cannes to seek seclusion as a hermit. However, he was too good at it, and soon lots of disciples turned up to see how he did it. As he sat in his cell, he was constantly interrupted by cries of "How's the hermit life going?" "Are you doing it now?" "What happens next?" "Peace and quiet are wonderful, aren't they? I said PEACE AND QUIET ARE WONDERFUL, AREN'T THEY?" And so on.
So if celebrating Mass as we recommended doesn't seem to be working, and you do decide to self-isolate, here are some useful tips.
An axe. In case anyone comes visiting. A sign saying "UNCLEAN!" should keep most people away (it certainly works for us in Mass), but there will always be Mr Nosey from church who insists on doing the Sign of Peace with poor unsuspecting hermits. That was one of the famous sufferings of St Honoratus.
Food. Get stuff that lasts a long time. Eccles cakes are like Tolkien's dwarf bread, and will keep for months. Meat doesn't really last: you may have thought of buying a hippopotamus and cutting a piece off every day, but we really wouldn't advise it. And nor would the hippopotamus.
It seemed like a good idea at the time.
Toilet paper. 20 rolls per day should be sufficient. Or use the collected works of Richard Dawkins (which is better than they deserve).
Hand wash or soap. Well, if you're on your own, there's really no need to wash at all, and nobody will notice that you smell like a [offensive stereotype deleted]. Still, do scrape off a layer of dirt every month or so.
Spiritually nourishing reading. From the depths of our hearts by Pope Benedict XVI and Cardinal Sarah, is a good choice, because it winds up so many people. Wounded Shepherd, by Austen Ivereigh, one of the people wound up by our first choice, is probably a waste of time, and should join the Dawkins books (see above). The Bible's quite a cracker too - plenty of sex and violence, some jolly psalms for you to sing while washing your hands (if you're fed up with singing "Happy Birthday to you"), and a truly apocalyptic ending, where St John goes to Patmos and unmasks the criminal.
Pontius Pilate sings "Happy Birthday to you".
