As far as last lines go, I have three lol I couldn't pick which one I liked best.
This is from Seaon's of Change where each part starts with Nick as he's giving his commencement speech at high school kind of in the same vein as Mel's with the journal entries.
As I walked back down to my chair I took one final look at the crowd, how different things were going to be for me now. I was terrified but open for the challenge. That's what life was all about.
This is from Shadow Woods:
“What are you staring at?”
I looked over at Kevin and smiled, this is something I was going to keep to myself for a long time until maybe one night over pizza and video games I’d blabber about it to Brian or something. Instead, I looked around the room seeing all my friends sleeping in various positions all over the place, including AJ who was actually in a ball on the floor and I said one word.
“Life.”
And this one is from The Apartment:
They grew to love each other and come together as less of a group and more of a family in this stupid, smelly one bedroom apartment that barely had enough light to see in the middle of a sunny Florida day, and when they would eventually make more than enough money to move out on their own, they would at certain points in their lives all miss this place. It was simple, it was plain but it was their home, even the ones who didn’t live there.
Kevin smiled, shut the light and closed the door.
