Why does Atticis make the children leave the house and stand in front of the Radley house?

I don't recall this, are you sure?

Oops sorry,

The night following the snowfall is bitterly cold. Scout wakes up in the middle of the night with Atticus over her telling her she must get up and go outside. Miss Maudie's house is on fire. Three fire trucks are trying to put out the flames, but they are hampered by the cold, and one of the hoses bursts. Atticus makes the two children wait by the Radley house so they are well out of the way. In front of the Radley yard, they shiver and hope that the flames won't come too near their own house.
