Where did the blanket that Scout finds around her shoulders come from?

The night when Miss Maudie’s house burns down, everyone in the neighborhood goes outside to watch the fire that was caused by a cold snap and Miss Maudie lighting a kerosene heater to stay warm.  Atticus shuffles Scout and Jem down the sidewalk away from the fire, and they stand to watch in front of the Radley house.  Scout is so engrossed in the fire that she doesn’t feel the blanket draped over her shoulders...

The night when Miss Maudie’s house burns down, everyone in the neighborhood goes outside to watch the fire that was caused by a cold snap and Miss Maudie lighting a kerosene heater to stay warm.  Atticus shuffles Scout and Jem down the sidewalk away from the fire, and they stand to watch in front of the Radley house.  Scout is so engrossed in the fire that she doesn’t feel the blanket draped over her shoulders by Boo Radley.  This action by Boo shows how tender and caring Boo really is.  Not only does he leave gifts in a knothole in a tree for the children, he also protects them and keeps them safe when he can.  Later, his love for the kids is really shown when he fights the vengeful Bob Ewell who attacks Scout and Jem. 

This incident is just another piece of evidence that shows Boo’s true character.  He is not a ghoulish, insane recluse that the town thinks he is.  His gentle nature really makes him a true symbol of a mockingbird.
