I remember this man very well. He was my age, very smart, easy-going, hard worker. He had a very heavy Swedish accent, and was a little difficult to understand at times, but he knew exactly what to say to make you laugh.
I thought he was awesome, because he could quote lines from Final Fantasy VII verbatim. He even had a Sephiroth cold cast statue on his desk.
He worked upstairs from me on the 100th floor; I was on 99. The first time I met him, I was helping move his computer equipment from the South Tower after we acquired RGL in '99. Unfortunately, he did not survive the attack.
He invited me out for drinks about a month before the attacks, and I didn't take him up on it, because I had to work late to support our upgrade to Microsoft Office 2000. One of those decisions I'll always regret.
