My mother the Hypochondriac

So mum decided that it was time to put the electric blanket on her bed for winter. She put it on and hooked it all up. That night she had a fantastic night's sleep and was feeling great - the heat had really helped her arthritic pain in her spine. She was ready to take on the world.
In the morning she went to turn the blanket off - it wasn't connected.
