ha! the Jehovah’s Witnesses caught me! they want to come back next week too! there really wasn’t a polite way to say, but you are a cult.
NEVER take a flyer from them, they WILL come back in hopes you read it and will be open to them the next time.
We had them in our neighborhood recently - as mean as it sounds if you even acknowledge them they lock onto you.....I made that mistake in PA. We were polite but definitely said “not interested” and didn’t take the literature.
