The last straw

Massive false alarm in the pig pen today when Pam, who is with piglet, was found to have made a massive construction of straw in her sty. This was in contrast to yesterdays efforts where she had made an enormous pit lined with most of the bale of straw given the day before.
 Today saw a large mound like creation made up from the bale given and the contents of three other bales taken from the wreckage of next doors sty where four bales had been carefully laid up and two naughty ponies had carelessly unlaid them. This equine vandalism has had to go unpunished as the naughty boys are at autumn riding school (like borstal but with whips) but this misdemeanor has been a bonus for Pam keen to win the porcine grand designs competition.
The one side of the mound appeared to be pulsating in a strange theres piglets hidden in here manner. Pam, not known for her geniality, was pacing around the pile making odd grunting noises (yes I know pigs are supposed to grunt but Magalitzas dont usually grunt they make a sound similar to Godzilla stubbing his toe) clearly on guard.
Yours truly decided that, given the evidence, a closer look was needed. Pam, a sow who does not suffer fools kindly, decided that private investigations of her pile was a definite no no and no amount of coaxing or Celtic oaths could persuade her that safe passage should be allowed. As I was about to try the time honored poke with a stick method something in the grey matter alerted me to the fact that the pile moved in a very strict pattern which meant that either the piglets were a highly co-ordinated display team or the movement was down to something else.
Like a plank of wood trodden on by a patrolling sow.
An organised person would have posted a pic of the mountain of straw and angry pork so you will have to make do with a picture of Reuben stood in front of the aviary with its winter covering being applied which might indicate some method in the madness that is my life.
