For Children: You will need to know the difference between Friday and a fried egg. It's quite a simple difference, but an important one. Friday comes at the end of the week, whereas a fried egg comes out of a chicken. Like most things, of course, it isn't quite that simple. The fried egg isn't properly a fried egg until it's been put in a frying pan and fried. This is something you wouldn't do to a Friday, of course, though you might do it on a Friday. You can also fry eggs on a Thursday, if you like, or on a cooker. It's all rather complicated, but it makes a kind of sense if you think about it for a while.

Anything that happens happens, anything that in happening causes something else to happen causes something else to happen, and anything that in happening causes itself to happen again, happens again. Although not necessarily in chronological order.

My favourite piece of information is that Branwell Brontë, brother of Emily and Charlotte, died standing up leaning against a mantelpiece, in order to prove it could be done. This is not quite true, in fact. My absolute favourite piece of information is the fact that young sloths are so inept that they frequently grab their own arms and legs instead of tree limbs, and fall out of trees.

'Stotting' is jumping upward with all four legs simultaneously. My advice: do not die until you've seen a large black poodle stotting in the snow.
