Thanks, everyone! And if anyone feels more comfortable sending me a private message, that's fine too. I'm not in this to judge anyone's answer, and I welcome input from anyone who chooses to answer. Given the nature of the class, I think the purpose of this exercise is to see how much my definition changes over time based on what all of you suggest (e.g. my definition may become more complete, as each of you suggests something new that I hadn't previously thought of).
After Tuesday, I'll post what I handed in, for the curious, as well as comments I may have on anything posted here.
