How creepy.

So there are some true weirdos out there. Today at school, I finished the quarter up and I went to the practice room to practice. I then got really hungry, and I had a gut feeling that I should probably go home. I went downstairs with my keys in my hand, and I on my way to leave the building I saw this guy, I'm going to censor his name and call him N. He saw me with excitement and hugged me tightly, and I didn't think anything of it. He was simply someone that just hugged me. I then ran into my girl as friend Shayne. I told her I wanted to play her a song that I learned. She nodded, and N decided that he wanted to listen to, so being courteous, i said okay. But it turned out that it was just N that came with me. It was awkward from that moment.
He followed me into the practice room, and I smiled in awkwardness. I started to play for him, and he got aroused it seemed. So in response, I told him that I only really practice piano and flute with my time, and I don't have much else of a social life, because I have no interest to do so. (AKA my hint of, don't even try to hit on me buddy.)
He then decided that I shouldn't practice anymore. I was PISSED. You don't stop me from practicing. I then got really upset, so then I basically told him I was going home. Practicing is what I was there for. So i went to grab my backpack, but he grabbed it before me. I went to grab for it because it was MY backpack, and I WANTED it. But he wouldn't LET me. He kept saying no, pulling the backpack away. I eventually got PISSED and gave up. I went to grab for the backpack again, and he again wouldn't let me, even though he had his car RIGHT next to him. Finally we arrive at my car, and he puts my backpack in my car, and I wave bye to him, hoping he would leave. He then grabbed me and picked me up, I struggled...and screamed, but he just continued to carry me, and put me in my car seat. I then waved bye to him again, but he put his face close to me, and i pulled my face away, touching everything he can. He eventually left, eventually but it took a lot of effort. I kinda sped out of school, and i felt anxious to go home.
I did tell him to stop, I hinted to him too, but he didn't catch it. I have a performance this Sunday, I'm scared.

I hope everything is okay on Sunday.
