When I was younger, I always wondered how the trees got leaves in the spring after they had fallen off during the fall. The most logical explanation I could come up with was that the fallen leaves magically floated back up to the branches of the tree and became green again. I would always get upset when my mother would sweep up all the dead leaves on the sidewalk outside our house because I thought she was stealing the tree's leaves.
I believed this until I was about 11 or 12 and finally realized that trees regrow their leaves every year.
