Everything Went Dark

You want the radio off. You study the radio to try to find the on and off button. You find it. You press it. Nothing happens, the radio stays on. You try again. And again. The radio stays on.

The radio crackled. You pause and try again. Nothing happens. You think it is best to leave the radio alone.
