That avrilo has something to answer for.

I. You have to look up page 123 in the nearest book to you.
II. Look for the fifth sentence.
III. Then post the three sentences that follow the fifth sentence
IV. Tag five people to do the same.

The nearest book to me this evening is The Faber Pocket Medical Dictionary. Don't ask.

Since it's a dictionary and short on sentences I have looked at the fifth definition and am posting the next one, which rather strangely is:

drug. Substance used as a medicine. D. addiction. A dependence on drugs which is beyond the subject's control. D. erruption. Rash due to sensitivity to a drug.

And so it carries on in a similar vein (well, it is a medical dictionary - groan). The person writing the definiton of 'drug' seems to be inordinately fond of full stops.

I'm going to tag my five newest friends here: frankofyle, kelki, Arnica, babooshka and rowtheboat (sorry row, I got you last time as well, hope you don't mind).
