Pigs on the wing

(part 1)
If you didn't care what happened to me,
And I didn't care for you
We would zig zag our way through the boredom and pain
Occasionally glancing up through the rain
Wondering which of the buggers to blame
And watching for pigs on the wing.
(part 2)
You know that I care what happens to you
And I know that you care for me too
So I don't feel alone
Of the weight of the stone
Now that I've found somewhere safe
To bury my bone
And any fool knows a dog needs a home
A shelter from pigs on the wing

("Animals", 1977)
