Choose! Cold or Hunger?

A man was walking down the street, wearing warm clothes in the cold foggy night. While walking, he saw that a boy was foraging for food, clad in shorts and a torn shirt. The boy was shivering from the cold, so the man was cursing the fog.
But I could feel the heartbeats of the boy. They were thankful to the fog, due to which the DOG couldn’t see the food five minutes ago.
