The situation:
An older lady and a teenage girl, wielding pamphlets, knock on our door.
Lady: Hi, we're members of_ church, which has just opened up in the neighbourhood.
Me: Oh, we're not religious.
Lady: Well, then, you're just the people we want to see! Have you considered...
Me: We're not religious and we don't want to become religious.
Lady: Oh, well, religion isn't everything. You could just join our...
Me: We don't want to become members of a church.
Lady: Well, will you just read this pamphlet?
Me: No thank you.
Lady: Can I just leave one in your mailbox?

Proselytizing religions really get on my nerves, and I feel that I was as polite as necessary to someone who wouldn't take the hint that I wasn't interested.
