Man I'd cry if you hadn't hurt me so hard

There wasn't a lot of cash in your wallet when they beat you up for it.
And perhaps that's why they hit you quite so hard.
And you lay on the ground barely daring to breath, imagining a rescue.
In the end you levered yourself up, and leant on walls to the corner where, with the aid of a lamppost, you hailed a cab, to take you to Accident and Emergency.
You paid with a bill from the roll you kept hidden and stumbled inside.
