I had some awesome ones, years ago.
They rocked up, I said no thanks, atheist household.
Then they spotted ds, then aged about 4, playing in the garden.
'oooh hello, yoo hoo Crowboy! So lovely to see you again!'
Me: 'er... Slightly weird. How do you know my son's name?'
JW: 'Oh I'm great friends with his childminder!'
Me: 'ah OK, she's lovely, isn't she? Anyway, not interested, have a good day.'
Mentioned it to CM (Pakistani Muslim & fairly new to the UK at that point).
CM: ' Oh yes. They'll be the ones who came round last week. I let them in for a cuppa. Seemed rude not to... Anyway, they were sooo friendly but it was totally awkward. Won't make that mistake again!'
A few months later the JWs turned up again.
This time their opening gambit, as I was politely explaining that I was an atheist, not interested, thanks & bye, was to ask if I was really happy with my dc being cared for in a house where 'Jesus Christ was denied' .
Pointed out that CM & her faith had a damn sight more time for JC than I did. I may have been rather peremptory at that point in ordering them Orf My Land.
