Martin's virtual lair

A few days ago I received a much belated letter, 23 years to be precise. I should already have received it in 1987 at the age of six, when I was staying in Berkeley, California with my family for nine months. During that time I started the hobby of collecting stamps (long since discontinued), so I ordered free souvenir pages of the US Postal Service with some stamps. At the time the letter arrived at our house in Berkeley, however, we have already left the US and returned to Germany.
