Stan The Man muttered:

What a rude woman you are. I have been gardening for 40 years. And I
make my living from horticulture. Being pompous certainly doesn't make
you right - although it might make most sensible folk choose not to
engage you in conversation, leaving you with the false impression that
you are always right. But you and I know different.

Indeed...

As Dorothy Parker says 'You can lead a horticulture, but can you make her
think?" :0))

Why don't they just exchange e-mail addresses and keep their bilious
correspondence on a more private and agreeable footing for the rest of us,
who'd just like to discuss gardening?
