Joe lived alone and liked it that way. Joe never had visitors and never visited anybody. Since joe never left his house, he had supplies delivered every 2 weeks. One dark stormy night, Joe got fed up with life, and turned off all the lights before going to sleep. The next morning, they discovered that, as a result of Joe's actions, several people had died. Why?
Was Joe agoraphobic?
Maybe he was. How he feels about open spaces doesn't matter :)
Was Joe a lighthouse keeper? :)
