Nostalgia. The memory that gives me the most sincere smile while rolling a tear down my cheek. That is the feeling that embodies me. Those moments when that person was there or everything fell into to place just right and existence became worth it. Those moments are gone, but you feel them even now. Times might be hard now, but these gems are anchors in any storm. They happened without searching for them, and in unexpected places. So you know, they'll find you again as long as you keep looking.
So maybe nostalgia isn't the right word then. As sappy as it sounds, maybe Hope is the right one. Keep your Despair, Ame. That's just the rough that hides the diamond.
