Don't Blame Me-The Silver Watch

She walks alone through the park on rainy days. She doesn't talk to anyone, but sometimes she'll turn her head to the right and smile, as if someone is walking with her. She walks around as if she has all the time in the world, never even glancing at the people passing by.
This woman never seems to age, her dark brown hair and deep green eyes never seem to flicker as if her life is coming short. Not a single strand of grey hair is ever seen as her hair blows freely in the wind. She is young, but old, and every few years she seems to vanish into thin air, until the ones in the town that know her name have perished, and the ones that don't, won't suspect a thing.
Though she may be beautiful and seem almost happy with the perfect life, the smile on her face only explains a little bit about her past. If you look at her in the perfect angle sometimes you'll see something, something you never thought you'd ever see in a million years. You'll blink, and the girl will vanish. Her name lost in the void of life.
