That moment you think your computer has crashed/frozen... Then realise the batteries in your mouse has died.

Found a sandwich bag of AA batteries in the common kitchen freezer. Not sure what to do.

being the good guy that I am I was helping out a family member over the phone. Frozen computer was the verdict... Eventually it turned out the computer wasn't frozen at all, the batteries of the magic mouse had died... thanks for wasting my valuable time! I then told em I would only help if they used cables for everything, including wifi. It took 3 weeks for them to realise Wifi cables don't exist. revenge can be satisfying sometimes!
