I read yesterday that if event A happens at the same time as event B, then your subconscious will link the two. If your dog collapses while you walk him under a willow tree, then future glimpses of willow branches will remind you of poor Fluffy's demise.
I fear that I will henceforth associate the majestic Saqqara step pyramid
with 1). trying to sell my Google stock at the start of the trading period, via a Sidekick hiptop running lynx (text-based browser) with a lag time of several seconds, and
2). stabbing stomach pains ("Mummy's Tummy" according to the guidebook). Julie warned me that the so-called bathroom near the pyramid is actually a trailer whose walls were covered in shit. After the stomach pains set in, I was very grateful for that bathroom.
