Ah, the d10! While you aren't actually a true regular polyhedron, you are the only die that makes logical sense--metrically speaking. Chances are, others see you as over-analytical or a goody-goody. While that may be true, you also have a gift for patience and tolerance. Growing up you probably had a calculator wristwatch that you never really needed to use (since you were faster on your own), and you probably aced all your classes (except for gym). You use the metric system almost exclusively, but are able to quickly convert in mid-conversation for the sake of your backwards Imperalist friends. You've coded in at least two different programming languages, and have created more original gaming systems than you'll ever admit. You're generally not a show-off, but you do take pride in being called either a geek or a nerd.
While parts of this description are frighteningly accurate, I actually don't much care for being called a geek. I find the connotations with the original meaning of the word distasteful. Yet I will occasionally use the term "Alpha-Geek" about myself, when appropriate. Weird.
