Once upon a time, one star that was very sad, the reason was, that wasn't anyone was watching it. When someone did, immediately look away as if of something disgusting were there. It spent a lot of time trying to find the reason for his misfortune. «Is it because I'm so small that they can´t see me?» It instantly dismissed that possibility. «Maybe I'm not bright enough?» The star, on the verge of crisis, decided that its existence wasn't necessary, and that it would do a great favor to everyone if it disappeared. Then at some moment when nobody waits, it would explot.
End.
The name of that star is Sun.
