Oh Smiddy - I like to give them my full name and address - you end up with these wonderful tumbleweed moments. So these zealous preachers are... hmmm... where? And their response is... silence. It's very peaceful and relaxing.
It's not really as much faff as this but keeping vampires at bay ain't that difficult. You just pull out your Bible and slap 'em with the Scriptures.

Anyway be interesting to hear if anyone gets back to you. I'll do my letter when I've finished my next vid. Nearly there. Just around the corner - I hope. :)
