It happened a few years back. An old male college teacher was seen eating alone in a corner during a College Faculty luncheon. Some teachers who saw him attested that he looked a bit strange and unusually quiet. They invited him to join their group discussion but he just gave them a blank stare. After a while, he just disappeared and nobody noticed him go out of the room. The bizarre thing about it is that this certain teacher was already in the hospital slumped on his deathbed at that very same moment. A few hours later, he was dead. When his desk was cleaned by his fellow teacher a few days after his death, the teacher was so shocked to find a note personally addressed to her, thanking her for everything. (From Owen Jaen)
