I have a feeling I've made posts before in which I list his numerous good qualities, but I'm going to do it again this year anyways. Please feel free to add to the list, since there are a lot of qualities indeed to list, and I am a Bear of Little Brain (probably ™).
Andy is kind, gentle, patient, and caring. He has a devastating sense of humor and a way with words. He has excellent taste in music and books, and can MST3K with the best of them for movies and TV. He is brilliantly smart, and a wonderful teacher. He has a way with animals; I've seen a dog who was noted to be terrified of men walk right up to him and ask to be petted, and our cats miss him when he's on travel and love him when he's home. He understands the value of teddy bears and other stuffed animals, and when the hotel cleaning people do special things with Cassie, his stuffed calico travel kitty, he sends pictures home. He understood how important college was to me and let me spend nearly a year away from home in order to finally obtain my degree at the school which I had never ceased to love. He takes awesome photographs. He is a dedicated friend who does anything within his power to help friends in need. He's one of those people who, when he says "Call me at any time," means it. He knows when to encourage and when to advise a person to walk away gracefully. He works hard, and some of his efforts lead to nothing shy of miracles.
And when it comes to talented, he's multi-faceted. The first one I ever encountered was his raytracing, an art form which translates math into images. The most enduring roses I've ever received were featured in a spiraling vase in one of his raytraces. The most recent of his hobbies which I have been fortunate enough to be on the receiving end of are his tessellations, all of which begin life as a single piece of paper, none of which are cut, taped, or manipulated in any way save folding. Some of his other origami is linked from the tessellations page and is also worth looking at; included are mobiles for the children of various friends and some of the more traditional forms of origami.
I'm sure I'm forgetting some things, because he is just that incredible of a guy. I am so grateful to have met him, let alone shared his life with him. And I love today, because it means the world has had him for another year, and been a better place for his presence.
<sappy>I love you, Andy</sappy>
