Avogadro Dimitri Alexander

I had a cactus in college named Avogadro Dimitri Alexander. Dimitri was a tiny thing, which is to say he was no Saguaro. But he was a good cactus, and sharp as a tack. He survived most of the abuse that a college lifestyle can dish out to a poor little plant outside his native environment. I say "most of", because he did die eventually, of extreme neglect.
