I am a pharmacy student and during lunch, I decided to step outside and read a graphic novel. As I was peacefully reading, this man came up to me and sat down on the same bench.
He turned to me and asked, “Excuse me, would you be interested in doing something nice for a total stranger?”
I definitely was not interested in such a thing since I figured it wouldn’t be something straightforward so I said, “In what way?” 
He thought I had said, “No way” and he started to leave when I stopped him. I stopped him so he wouldn’t think I was being rude, which could ensue a dangerous situation.
He then went on to tell me he is an international student who was going to be sent back home but I could help him. He needed me to sign a loan for him.
I figured it was some sort of scam so carefully and politely explained that I couldn’t help him. He continued to talk to me for a few more minutes and asked me if I was a pharmacy student. 
He stood up, shook my hand and left.
This wasn’t too strange and I wasn’t too concerned about it until that night.

That night I went to work out at the campus gym. As I was driving to the gym, I saw this same man walking down the street. He recognized me. I looked in the rearview mirror after passing him. He stopped walking and turned around, staring at me as I drove down the street.
I know I’m probably being paranoid, but now I think I’ll read my graphic novels inside the building.
