Ok, this one is REALLY CREEPY. So yesterday I was finishing some maths homework in the library at school, as I normally do most afternoons. About 5 minutes later, some kid walked in, wearing a hoodie. He had it done up tightly that only his eyes were showing, and he just walked over to me. Then, he grabbed my maths stuff and threw it all on the floor. I was like "Why'd you do that?", and I got no response. Then he just walked away. About two minute later, I saw him staring at me from a distance. I went up to him, and asked him who he was. He just said "Your worst nightmare". By this point I was getting tired of him, and tried to pull his hoodie off to unmask him. For a little kid, he was actually pretty strong, and kicked me in the stomach, as I fell to the floor. I then walked away and went back to my maths homework.
Once again, he was standing there, just staring at me. I got my phone out, and tried to take a picture or a video of him. He then grabbed my phone, and threw it on the floor (luckily I have a protective case so my phone suffered no damage). He then said "Leave this place", and I was like "No, [snip], I'm trying to do my homework" He then said "You'll suffer for your ignorance, fool". By this point, I just couldn't help but laugh. That stopped when he hit me in the face, and I now have a large bruise on my left cheek (really hurts too). I managed to get a short 18 second video of him, before he grabbed my phone again (I saved the video, so it's all good). Then he said that my actions will lead to suffering, and with that, he just walked away.
I am now worried, as I've done nothing to provoke this. He just came up to me and threw my maths stuff around. I don't even know him. Thoughts?
