I lost the plot with 2 JWs today.
We do have a sign etc.
But they hammered on the door, ignoring the doorbell.
I'm one week post spinal op, I've been let home on the basis that as an exHCP I will follow the 'rules' I've been given, one of which is only doing the stairs once a day. So once I'm down that's it.
Anyway as I said they were hammering on the door, with us having family in the army overseas and in the police…and as we know sadly accidents happen. So as it takes me 10 minutes at least,to get out if bed,find my glasses and get down the stairs I assumed the worst when I could still see people at the door.
Do I know God?
(If God knew me she would have warned me, and I wouldn't have left my phone, kindle and ipad upstairs.)
I'm not sure how often I used the word fuck in telling them to fuck off and I'm Irish I like swearing and I'm good at it.
Once I'd stopped for breath, the male witness observed that I was still in my PJs and this was a sign of depression, and with my 'foul' mouth it was clear I needed help. . . 
One final Fuck the fuck off and I slammed the door in their face. The buggers knocked again. . .
Now I grew up with JD neighbours so once they started knocking around here I got in touch with the local Kingdom/ meeting hall and asked that we not be called on. We seem to have fallen off the list. . . .
Worst of it is we actually have a Mormon Temple locally too. So I can expect a visit from them in the next few days too. . .
They clearly keep an eye, and if you have one you have the other within days.
Cold call sellers I have a minuscule of patience with, I'm polite, say no thanks and shut the door.
