I was just walking and then i saw it. Beautiful. The trees were blowing in the wind. My hair. My hair was free, blowing in the wind, much like the trees. But I still saw it. The little concrete table in the middle of the woods. I set out to find it and finally, I did. The excitement was phenomenal. I mean, could you imagine, sitting out here, having a picnic, reading a book, writing. Oh, it was amazing. I didn't want to leave, but I had to. But I had a plan.
The next morning i went out to the table with a basket with a sandwich, grapes, an apple, and peanut butter for the apples. I also brought my favorite book with me. Hatchet. As I was reading the wind started picking up so I had to go. But, I was determined to finish my book out there. So i kept going out there everyday.
Option 3: The phrase acts as a noun that is the subject of the sentence.
"Volunteering at the animal shelter in my neighborhood" is a gerund phrase (It begins with a gerund, the "ing" word, and includes others modifiers and objects), and gerund phrases always function as nouns. Therefore, the phrase in the passage acts as a noun, which at the same time is the subject of the sentence since it's what's being discussed.
Dally chooses to die because deep down inside, he cannot live without Johnny and the pain of his death and not having Johnny around anymore is just too much to bear. He also feels in some way, a little guilty. In a way, his act was a bit cowardly. His friends have to live with the death of Johnny, just like he would if he didn't die. Now his friends have to live with the death of Dally too.
