speaking of Potterism before the Potter twins. The way the twins put it
was, 'Our family is responsible for more than its share of the beastly
thing; the least we can do is to help to do it in,' which sounded
chivalrous. And another way they put it was, 'We're not going to have any
one connecting _us_ with it,' which sounded sensible.

So they joined the Anti-Potter League, not blind to the piquant humour of
their being found therein.

Mr. Potter said to the twins, in his thin little voice, 'Don't mind
mother and me, children. Tell us all about the A.P.L. It may do us good.'

But the twins knew it would not do their mother good. It would need too
much explanation; and then she would still not understand. She might even
be very angry, as she was (though she pretended she was only amused) with
some reviewers.... If your mother is Leila Yorke, and has hard blue eyes
and no sense of humour, but a most enormous sense of importance, you
cannot, or you had better not, even begin to explain to her things like
Potterism, or the Anti-Potter League, and still less how it is that you
belong to the latter.

The twins, who had got firsts in Schools, knew this much.

Johnny improvised hastily, with innocent gray eyes on his father's, 'It's
one of the rules that you mayn't talk about it outside. Anti-Propaganda
League, it is, you see ... for letting other people alone....'
