Back to school...

Now then class, take your hands out of your pockets, stop talking, stop chewing, sit up straight and pay attention.
And you boy, see me after the lesson!

Now, who can explain what this simple equation amounts to; properties, components and values?

Come along now, it's simple stuff and I've been through it all before.

No takers...?
Not even a guess...?

Well I must say, I'm very disappointed.

Very well then, the answer is I am doing too much damn work and nowhere near enough fishing.

Class dismissed!
