When Wesley ran over his wife with the farm tractor it was hilarious. Not that it wasn’t a tragedy, but Wesley couldn’t help but see the irony in the situation. He was sure Cassandra would have seen the funny side as well. If she was still alive.
He had just taken the tractor out of the shed, apparently to feed out some hay to the cows. Cassandra was hanging out the washing on the line at the back of the house. She was hanging out the ham bag at the time. The ham bag was a cotton bag to put the leg of ham inside to keep it moist. They had just finished their Christmas ham, so the bag was in need of a heavy rinse. And at that precise moment of her hanging out the ham bag, WHAM! Wesley ran over her with the tractor. There was blood all over the place, including on the ham bag! On the ham bag! It had just been rinsed of bits of meat, and look at it now! It was hilarious.
Wesley drove the tractor back into the shed and went off to the pub to get totally drunk. Cassandra would no longer be leaving him for Farmer Judd next door.
