a creeper behind a friendly smile?

Today was a very sleepy-looking day : at the end of the 7th lesson i was a zombie with a beating heart ,after that i  walked to the library and while doing that, i thought that i was being stalked. Soon when i was on my way to studio ,i looked back to assure myself that it's all in my head but the person in black was still behind me .I started walking faster and several meters away from the studio and heared that a person behind me was walking faster too, soon the mysterious person was only couple of centimeters away from me .I hoped that if i would walk as slow as i can, the person behind me would just walk ahead of me. Unfortunately it didn't happen: the person started talking to me like i was his friend and i think that this was the most awkward situation ever. The stranger wanted my phone number ,he didn't get it  :)  ( i was freaking out, for the obvious reasons)
 When i was in studio , i had to make a decision  : will i perform on a concert or not ,i hesitated cause i' m still hoping i will get the adrenaline rush while perform sadly it hasn't happened lately ,now it's just a bit different reality and a strange calmness .
