Strange Situation in the Hallway at School. Why Did These Guys Do This?
I'm a girl in my early 20's attending university. Yesterday, after my classes were finished and it was the end of the day (around 5:30pm) I was walking through the main building's hallway to go home when a group of tall black guys (maybe 4-5) were walking in the opposite direction towards me. (I'm mixed with black btw) Anyway they looked me over as I past them, and then one of them suddenly grabs my arm and says "hey, you remember me, don't you?" These were all strangers so I was really frightened and said "no" (obviously). The other guys were saying things too but I just remember being so scared and finally freeing my arm, and walking away really fast away from them. I still heard their voices close behind me, shouting at me for a bit and I actually feared they were following me. But I didn't want to run and cause a scene since the hall was not empty, there were a few people sitting on benches against the wall or walking past me.
Luckily, they didn't follow me but honestly, I've never been so afraid in public in my life, like just the fact that that happened in a hallway with other people makes me really uneasy. I wondered why no one stepped in too. :( Am I over-reacting? What should I have done? Or, what should I do if a similar situation occurs in the future? Much thanks.
