Stalked by my friend

Chapter 1

    My name is Liz  I am 19 and I have 5 best friends there names are Olivia, Reilley, Conor, and Logan  and we have known each other for 5 years but it seems like longer.
    It's a cold fall evening in Marshall Michigan the year is 1991 and school is a month away  it seems like summer has just begun but time flys when your having fun. I'm on my way to Olivia's house she is having her 18th birthday party  I'm helping her set everything up as in decorations food all that fun stuff :p.  
    I'm almost to Olivia's house I have one more block to go. For some reason I feel like someone is watching me but it's probably nothing, Olivia is sitting on her front porch reading as she waits for me. I got out of my car and locked it I walked onto the porch and I noticed that she was listening to music. So she probably doesn't know that I'm here I walked around the porch to where she was sitting and pulled her seat. she screamed bloody murder, she pulled the head phones out and turned around and saw that it was me. I was dying of laughter,  " Liz that wasn't funny!"
"Yes it was you should have saw your face." I said laughing
" you almost gave me a hart attack!"
"Sorry!"   
"Yea right!"
"I am"
"Come on we have work to do."said Olivia.
      We went inside and I went to the kitchen to start cooking the food and Olivia went to her room to grab the decorations and to change. But before I could start cooking Olivia screamed I dropped everything and ran up the stairs down the hall and into her room and she was standing in front of the window looking towards the road shaking with fear.
      I walked over to the window and looked at the road ,a person in black,He was just starring at the house I grabbed my phone from my back pocket I clicked the home button and swiped the screen,typed in my password and dialed 911 when the operator answered the phone I was screaming "there is someone in front of my friends house he is in complete in black please help."
"Mam the police are on there way!"
"How long!?!?"
"2 minutes if you want you can stay on the phone with me."
    The police finely got there but when I opened the door the man was gone.
       "Hello officer."
"Hi mam, did you report that a man was watching you and your friend?"
"Yes, when you guys turned the corner he took off I didn't see where or which way he went." 
"Okay, I will patrol the road later around 10 ish and 12. another officer will come around 5 and park in front of the house." 
"Okay, thank you officer."
"No problem."
Olivia and I went back inside we went upstairs and I helped her pick out a party outfit for her birthday party.
