Without trying to steal Neil's thunder, I'm sure he doesn't mind sharing the misery, since, well, you know...
About 3 years ago, when my wife and I got married, the day after our wedding, we embarked on a 7 day Carribean cruise for our Honeymoon, on the 2nd day, we were on shore in St. Thomas. We went into the Hard Rock Cafe because I have a buddy who collects Hard Rock pins, plus, I usually try to buy a HRC baseball cap from wherever we travel to, so, while my wife is looking around for a pin and hat, my back was hurting pretty bad from the walking we had done, there was a chair nearby, not at a table or anything, so, I sat down for a minute, well, immediately, a HRC emplyeee told me I couldn't sit there, rather than argue, I decided we'd just walk outside and find a spot to sit for a minute, well, as soon as we exited the doors, it had rained and the bare concret was slippery, my sneakers slipped completely out from under me, and my head fell straight down, from my near 7 foot tall height, directly onto the concrete, my wife told me later it sounded like somebody had split a coconut. I apparently lost consciousness, and when I finally opened my eyes, I didn't know where we were, what had happened, nor that my wife was my wife! Imagine that, how my wife must have felt, wondering if her 2 day old husband in a split second had become a vegetable.
(Not a big stretch for me though...)
Now, the story I related above, is from what my wife tells me, since I have no memory of that day, my WEDDING, nor my wedding night, or honeymoon for that matter, nor do I remember anything for a couple of days before and after the fall. I had amnesia, though, as it turned out, thankfully, temporary. My memory of my life before the fall, excepting immediately before is fine, as is my memory now, but the fall, and a few days before and after, I still to this day have zero memory of. The cruise ship of course left without us, we were stuck in St. Thomas in the hospital for another week, until I was OK to fly home, then we had trouble since my passport was on the shp which had sailed away.... Anyway, the doctors said I had suffered a severe concussion with amnesia. To this day, my wife swears we ARE married though...
Now THAT is one heck of a honeymoon story, which just happens to be true.
Sorry Neil, but your concussion got me thinking of my own.
