Gifts in a Tree?

   As Scout was heading home one day, something caught her eye that made her go back to in front of the Radley place. There, there were two live oaks that stood at the edge of the Radley lot. One of the trees had some tinfoil that was sticking in a knot-hole just above her eye level. From the hole, Scout took out two pieces of chewing gum. Before Scout ate the chewing gum, she observed it to make sure that it was not poisonous since it was from a tree that stood at the edge of the Radley lot. She smelled the gum and licked it. When nothing abnormal happened, Scout just ate the gum. Later, Scout took Jem to the tree with her, and they found another thing in the tree. This time, there were valuable Indian-heads.
   There are many different ways people can view the repeating situation of Scout finding objects in the tree. Some people may find this situation interesting, and some people may find this situation just weird and creepy. Personally, I find this is situation both interesting and weird and creepy. What Scout found in the tree that stood at the edge of the Radley lot are somewhat normal things such as chewing gum and the Indian-heads. However, it is also unexpected since who would find these things in a tree? What I am thinking right now is if Jem and Scout are right about Boo Radley being this scary person that they have always imagined him to be, this may be his way to lure them closer to the house, so he can capture them and kill or torture them. He may be doing this to lure them closer to the house, so he can set up a trap that can result in him getting payback for when Jem touched his house and possibly disrupted the quietness of it as after all, it was said that Jem and Scout saw a tiny movement from the house after they ran away. If not that, I have no other theories. My head right now is just stuck with the thought that Boo is a bad and scary man who is planning to lure Jem, Scout, and anybody else into his trap just to capture them and do something horrible to them. If not, what could these objects in the tree mean? Is this something Boo is doing to try and capture Jem, Scout, and anybody else to get revenge for when Jem touched his house? Hopefully we will find out soon...
