"Friends"

The caveman was sitting by the fire staring into the flames. 
How is it possible that the fire which makes him warm and helps him survive the winter might also be the same fire that could destroy him with the heat of it's flames. 
This morning when he was out hunting he saw in the distance a big fire. 
The fire destroyed everything in it's way. 
Animals were running aimlessly without knowing where to go. 
At this time nature was simultaneously the enemy of the animals and his friend. 
It was very easy for him to catch a deer who was running in his direction. 
He knows that the same fire, who on that moment was his friend, also demanded he leave this place because after the fire there would be no more animals and nature for a long time. 
His cave was a safe place but he still had to go out for hunting even though nothing would be there. 
It was an unequal battle he would never win. 
The caveman realized that he has to live with friends and enemies. 
Sitting by the warmth of the fire, staring to the flames, the caveman decided never to come too close to his "friends"
