Then, read the Pickaxe (1st edition) online until you get paid, and can buy
the second edition. Link:

I sat and tried to come up with explanations for everything, but I'm too
tired. I think most of your questions will be answered by reading the
sections "Classes, Objects and Variables" and "Modules."

As for extend, read this:

http://ruby-doc.org/docs/ProgrammingRuby/html/ref_c_object.html#Object.exte=
nd

There are a couple more examples that might help you get the gist of extend=
.
Remember, *everything* is an object, even the definitions of the classes
(they're just constants).

Ask what isn't clear after that, and I'll try again.
