It might happen one morning when you wake up home alone. This could be normal, depending on your situation, but this morning will be different. While your environment will all seem exactly the same, you will notice that everything is quieter than usual. If you go outside, you will notice a distinct lack of anything like birds, insects... Or people. As far as you travel, you will not encounter another sentient being. The entire world will be intact, it is just empty... Except for you. Original author unknown
