My old house number was 1004. Exactly five blocks away was a trade association that had the same 1004 street number. I used to get mail for individuals who worked there all the time. I figured my mail-sort box was either just above or below the mail-sort box for this trade association. Fast forward over 5 years and this crazy madman who used to work there is now a good friend. Oddly enough, I had to fly to TPA to meet him for the 1st time!
And btw, if his stupid sister starts passing around naked baby photos of him at the next London Do... avert your eyes at all costs!
