At any time
Do you remember, as a seven year old, writing a letter to your grandma and addressing it like this:
Grandma Contrarian
24 Argumentative Road
Whingeing
Essex EX4 5FU
England
Britain
United Kingdom
The World
The Solar System
The Western Arm
The Milky Way
The Universe
THE MULTIVERSE[1]
- ↑ Ok I am making this up clearly the (preposterous) cosmological hypothetical on which this relies was not widely known in the 1970s and certainly wouldn't have been known to a seven year old,
