Sure, let me check my memory banks...  OK.  Bitcoin is a form of virtual currency.  It’s a new digital unit of account that can be stored electronically.  There are a variety of people who use it for various things, but generally Bitcoin is used for buying and selling things online.

Sure, glad to help!  What I’ll do is give you a live demo of how to set up a bitcoin wallet, and then I can walk you through a transaction of real bitcoins!  How does that sound?
