What should I do? *UPDATE*

Okay, so if you have no idea what’s going on, please refer to this question I asked earlier: What should I do?

So. I talked in length to my family and friends about the notes left on my car. Because both instances had occurred at school, there was no visible damage done to my vehicle, and no threats were made, my parents encouraged me to just leave it alone and not bother campus security. Simply because, for all we know, it could just be friends of mine trying to mess with me. (My best friend and her boyfriend were getting tickets for my show AT school the same day that the first note appeared on my car. Maybe it’s them?) Three days go by. I walk out of rehearsal. I walk out to my car, and I see this note: 
Now, for reference, here is how “close” I was to the line.
Also, on this particular night, we were rehearsing in a classroom. I parked in a lot that had hardly any cars in it. If this is someone who “tapped my car” they could’ve parked ANYWHERE else. However, this note doesn’t say anything about hitting my car, so I don’t know why someone went that far out of their way to leave a note, when PLENTY of other college students park FAR worse than I do. My parents then assure me it’s probably my best friends pranking me, and I leave it alone. Then, last Monday, I only had one class that let out very early. (I was in the building for half an hour, tops.) Then, I drove around with my friend all day, and we went to the mall. At one point, I suggested to my friend that we go to her boyfriend’s house before dinner. She says that she doesn’t really want to go there just to then go out to dinner immediately after, so we continue to walk around the mall. (But she had been texting someone the whole time.) Upon getting back to my car, we see this note: Granted, my friend and I don’t know if it was there since school and we just didn’t notice it until we got out of the mall, but it seems unlikely. (We were on the highway going 75 during the day. Even under my wipers, I assume it would have blown away or would’ve flapped in the wind and caught my attention.) Then, I FLIP out. I FaceTime my mom, and tell her that I think I’m being stalked or something. My friend and parents both assure me that it probably happened at school, and we just didn’t notice it until we got to the mall, or that whoever saw my car at the mall thought “Hey! It’s that car from school we always leave notes on, let’s leave a note here, too!” And the funny thing is, I DID park kind of bad at the mall. My friend and I were joking about it when we got out of the car and joked about another note being left. My dad thinks my best friend found time to do it without my noticing, and my mom thinks that my best friend texted her boyfriend and had him put it there while we were in the mall. So, now I’m beginning to think it’s them, but I don’t know. So, anyways. That’s the update!
