called "Sol" . And everytime you are in a certain position toward that star , all the humans, that live on you, become completely mad 
And I should say, of course there are four special positions in one of your rotations around that star
, because there is an angle of about 23 degrees between that rotation and your rotation around yourself. But the strange 
thing is: It is not at the moment of those four positions, not even at one of them, but only when one of them has passed and then when you turned another 10 or 11 times around yourself. But the story becomes stranger and stranger.
It happens not even everywhere on you at the same time. It only happens on whatever what place on you, at the moment when that place is exactly at the opposite posotion of you as that star is, so it's completely dark there.I find it almost unbelievable and completely un-understandable (if that's an understandable word) but then it happens that humans are having big party's with champagne and fireworks, they hug and kiss each other, and even if they never say a word to each other, at that moment they are close friends and wish each other all the best wishes.
Please tell me, Earth, what's the matter with you
Blessed are those who can give without remembering and take without forgetting.
You should try it sometime.
