One afternoon i was sitting on the back verandah of my sister's farm, sipping a cup of tea, reading a book and listening to the water from the river down below. after an hour or so i got that strange feeling you get when you feel someone looking at you. I looked up but there was no one there and i kept reading. i looked up again, and there was a huge diamond python coiled around the top of the verandah post. I froze, and just sat as still as i could watching it, not wanting to scare it into action. I noticed it seemed to be jerking its head in a strange way, rubbing it back and forward on the post. it was as if it was scratching an itch, rubbing its head back and forward. after a while i could see it was shedding its skin, slowly rubbing back and forward, peeling off the old, dry, transparent skin as the new improved snake emerged.

After a while my sister came out and i whispered to her to watch out.

She laughed and said, oh, dont worry, that's Fred, he lives in the roof. we like having him here, he keeps the rats and mice away.

what did fred look like?
