Answer:
The Pedestrians are free to come and go and choose the way and time they want to walk. On the other hand, the people inside their houses are considered to be in a graveyard, are compared to the dead, with no life, activity or freedom. Specific textual evidence:
What Leonard Mead loves most in the world is taking solitary evening walks through the city. At intersections, he peers in all directions, choosing which way to go...on these nights, he´ll walk for hours, passing darkened houses, whish is like "walking through a graveyard"...all he sees inside are flickers of light, "gray phantoms" or murmurs from open windows of "tomb like" buildings.
Explanation:
The only character that really enjoys freedom is Leonard Mead; he is free to come and go at any time or to any place he wishes. The others are confined in their homes with no freedom at all, like the dead in their tombs, with no life, no movement, no freedom.
