Go outside and meet the large garbage truck.
Lie down and have the garbage truck run over your right arm.
The truck's tire should rip your arm from your body
Tearing at the muscle, pulling at the flesh;
Leaving erose hunks of raw meat where your arm was.
Reconcile yourself to not having your right arm.
It's not so bad. You can use your other arm.
There's more to think about than painful absence.
