From Pink Floyd, Animals, this is Pigs on the Wing, parts 1 and 2. I recommend playing the video below whilst reading the lyrics. This one never seems to go out of style and seems pertinent to oh so many situations. Use as you see fit.
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 buggars to blame
And watching for pigs on the wing.
You know that I care what happens to you,
And I know that you care for me.
So I don’t feel alone,
Or 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.
