Dancing and other relationships with pigs

The start of an ongoing rumination on our relationship with other animals. We are prepared to eat them so why not have other relationships with them too?
When I was about 5 or 6, people in Dudley still used to keep pigs in a sty at the bottom of the garden. It was a lad's job to feed them the left over vegetable peelings and they appeared to this sensitive boy then as very bright but potentially frightening individuals.
Since then as a grown up I have learnt that other people can be very bright but potentially frightening individuals.
