You can never be too careful.

I'm 17F. I was walking home from school alone and noticed a car following me for about 2.5 miles. I walked at a steady pace and kept my hands free, but I was terrified. The car was roughly 10ft behind me. I passed a row of houses, and the car passed me, and stopped near a row of houses about 50m away. I walked up to the houses, and the car came back, and parked about 10ft away from me. It was a BMW, black in color, with tinted windows and a crack in the front windshield. The driver, a 30 something year old male, got out of the car, and walked towards me. I was terrified, and I ran the 2 blocks home. Looking back, I see that I could have been kidnapped or worse, and I feel really scared. This was in the middle of the day. You can never be too careful.
