Ok, simple rules. Post a riddle, it has to be one that you made yourself, or one that is not posted from before. The next person answers the riddle, and posts another riddle. If you don't have any answer for a riddle, well, dont post

Also if you think someone else has got a riddle wrong, feel free to try to correct him!


Ehem:

I can be joyful entertainment.
I can be a desperate fight.
No man has ever seen me.
But I will be there every night.

What am I?
