Dose anyone find church groups annoying when they come to one’s house?

Not that I've had them very often, beside the occasional eruption of a bout of Jehovah's Witnesses, but I try to look at them charitably. They almost certainly don't really want to be doing it (certainly most JWs don't seem to witness for Jehovah with much enthusiasm), but are basically pushed into doing it by those who lead their church locally or denomination more widely. And the far more rare people who go door to door because they truly want to tell you All About Jesus, even if wildly enthusiastic, aren't going to be put off by your lack of interest either.

Yes they're a tad annoying. Don't have to buy what they're selling. But practice charity (which they ought to recognise is also a Christian virtue) by making them a cup of tea.
