Part 2 of my story

“How did you know I would be here?” Alexa asked, acting friendly.
“You sent me a note saying to meet you here.”
This drove her mad. Alexa didn’t send her a note. She knew exactly who did it, too. It was her old friend, Sylvia.
Sylvia and her used to hang out all the time in school and even after school. This was up until last year when Sylvia was reunited with some of her old friends that Alexa wasn’t fond of. Sylvia wanted to hang out with Alexa but Alexa didn’t want to hang out with her. Alexa secretly tried to hide this but she trusted too many people. One person told Sylvia and Alexa didn’t know who.
“Note?” Alexa asked trying to act bewildered.
“Yeah, this note”
The note said:

Hey Sandra,
It’s Alexa. I haven’t really gotten to
know you and I would really like to.
I usually go to the park at around one
in the afternoon. Would you meet me
there?
Alexa

The note proved it. She could recognized the printing from all the hate mail she got from Sylvia. Alexa was outraged. This didn’t even sound like her. Alexa hated meeting people. She hated people.
They heard rocks crunching beneath feet and turned around. No one was there.
“So do you want to come to my place for lunch?” Sandra asked.
Alexa was mad at Sandra. She knew Sandra saw the sandwich she was holding. Still, she pointed it out anyways and told her she had to leave. She was still making excuses to why she couldn’t come when they heard the footsteps again.
“Okay, Sylvia. Ha ha! Very funny. You can come out now,” Alexa sarcastically yelled.
Alexa turned around only to see her “friend” was gone.
“Oh, well. She must have gotten scared off,” Alexa said to herself.
Alexa was about to leave to go home but she tripped. That was the last thing she remembered.
