Was this an unannounced invasion, or did you have advance warning, Raven?
We did have a previous conversation something like this:
Mr Raven: What are you building?
Me: A supermarket.
Him: Oh! The Gang will want to go to the supermarket!
Me: No! They are NOT invading my supermarket. This is a sensible supermarket. They can keep well away until I have finished it.
And a few days later:
Mr Raven: Is it all finished now?
Me: Yes.
Him: <evil chuckle>
So... I was kind of expecting it. And I think, actually, that their presence improved the look of the place.
