Along came Sally and Other Creepy Stories

I was alone, all alone, all the time. No one ever talked to me, nor cared about me. I was a dateless nobody. That is until Sally McDaniel came to my school. "Oh great," I thought. "Another person to not care about me. Another person to think I was nothing." I was wrong. In fact, on the 2nd day of school, she walked right up to me and said "Hi" with that big smiling face of hers. I was in awestruck. I was in love.
The next day, she asked me to see her after school for a "date." I went, scared this was a prank. It wasn't, and she kissed me! When it was over, I opened my eyes to see her smile to get even wider. It made me happy.
A month had passed since we've been dating. We were in love, I was popular, I wasn't my old self. I wore matching clothes with Sally, ate the same food as Sally, had the same freckles up my nose and blonde hair as Sally. Everything was perfect because we were perfect.
But one day, I got into a fight with Sally. I don't even remember what it was about, but we were through. Martha Wellington asked me out that same day, and I said yes. On the date, we went to the movies then went to a Chinese Restaurant, Mr. Ling's, and that's where I saw her: Sally. Same exact Sally. Same hair, eyes, ears, clothes, freckles, bigger than usual smile. Her face was almost ripping. I walked Martha home.
I was asked out by 3 other girls this week. Ali, Kayla, and Julia. Apparently, Martha enjoyed our date. But each date, Sally found me. Her smile was bigger each time. Her face in pain, I could feel it, see it. But she kept smiling anyways.
I got a note taped to my locker on Friday. It said: I'm sorry I hadn't noticed you sooner. Meet me after school at Mr. Ling's. I thought it was another date request, so I went. It was from Sally.
"Did you miss me?" All of a sudden the answer was yes.
"Yeah,"
"I'm sorry, baby. Come to my house?" All of a sudden, I wanted to go.
"Sure." She dragged me into the woods, but I didn't care. I was in love. Who needed a real home, or the truth. I didn't care. All I wanted was Sally McDaniel. Then we stopped. Sally looked at me. Her face was torn, basically in half. From ear to ear. She was still smiling at me.
"I missed you. How dare you leave me? How dare you leave me?" I couldn't answer. "But that's alright. Everything's alright because I'll be gone and you'll understand me very well. You'll have my gifts. And you'll be loved by everyone. And you'll be thankful you met me... because you are..." And I blacked out.

"Hi," said my victim. He looked pleased to see me. "I'm Jack Nickleson. And your name is, beautiful?" So I said:
"Sally, Sally McDaniel. Wanna go out sometime?"
