Will you walk into my parlour? said the Spider to the Fly,
Tis the prettiest little parlour that ever you did spy;
The way into my parlour is up a winding stair,
And I've a many curious things to show when you are there.

Oh no, no, said the little Fly, to ask me is in vain,
For who goes up your winding stair
-can ne'er come down again.

It's times like this I wish I'd listened to what my Grandad used to say...
