A symbol because it's telling you what your child hood is about a exposition is in a essay and a allegory wouldn't make sense
1. Last winter they went skiing every weekend.
2. As a child I used to love Ice cream, but now I hate it.
3. It was raining heavily when we left the house.
4. She hadn't seen him for years.
5. He had been working there for two years before he moved offices.
6. The old house hadn't been painted for years.
Doodle was pushing himself too hard trying to catch up to his brother in the rain. So when he sat down next to a tree because he couldn't run anymore.
He died leaning against that tree, all flimsy and small like that red bird that fell out of that tree before, which was foreshadowing his death.
Good Luck! :)
