Chris wants to know, what thing (material possession) do you value most? I like to think that I don't place much value on things, but that's an easy question anyway:

I know from experience that when there's a fire alarm, this is the first and only thing I reach for (I don't wear it around the house). Spouse, cats, wedding band, in that order. It's platinum, and heavy; we liked the weight. Cat's is an exact match. The inscription reads "Senn and Kitty 2002" -- our online names, since that's where we met. It's getting a little beat up now, and I rather like that. It's a symbol and reminder of the best thing that ever happened to me, and is the only material possession whose loss would cause me lasting sadness.
Don't tell my fiance, but I would grab my glasses before a ring... I *really* can't live without them. If I was wearing them however, and had room to grab soemthign else, I guess it is going to be my camera. Not because the camera is so important in gneral, but at that particular moment it would become important. I wuold really be kicking myself if I was outside watching the building burn down and didn't have the camera there to document it.
