Thank you, BagginsBill, for taking the time to create this remedial introduction into class behaviour using a real-world model for me. It was very clearly done, and easy to understand. I've followed your suggestion and have printed out Chapter 9 of the Python 2.6.2 Manual (the one on classes), as well as your explanation.

It's going to have to be a long coffee break.
