Nathan was, is, will always have been one of my best friends, his death struck me pretty hard. We chatted pretty much daily for several years over ICQ. Played Diablo and Starcraft together for hours on end. Talked about life and philosophy. I was invited to his wedding, we had even made plans for a special dance.
I recall he once said I was the only person in the world he never got angry at.
I also remember sending a letter the day after the announcement (It came in the middle of the night for me living in Sweden and all), but I have no idea if it ever reached you, or if my tear ridden message sank into the Atlantic Ocean, much like Europe in the world of Fallout.
I sometimes dream about the little floating "Iguana Eater" icon turning blue again, hearing the Uh-oh! That means my friend is alive and has some new and interesting story to share, a wise perspective to add to any situation I might encounter.
I make sure to light a candle annually, for what it's worth.
His sarcasm and friendship will be forever missed.
