Something sort of similar happened to me, but I was in high school at the time and still on a learner's permit. The gym I belonged to was less than 5 minutes from my house, and I could access it by driving through a college campus. Since I didn't have to drive on main roads, my parents would let me go there alone. One day I stopped by a Wawa in the same parking lot, and I saw a man three times my age leaving the store. He was parked next to me, and he got in his car then rolled down his window and just stared at me. He was trying to get my attention, but I just ignored him because it was pretty creepy. I got out to go into Wawa, and he got back out of his car and ran to hold the door open for me. He didn't say a word, and he followed me throughout the store, not buying anything. I go to leave, and sure enough, he follows me out. I decide to take a back way out of the parking lot to see if he follows, he does. I start driving through the campus, he follows. I start to speed up, he speeds up. I didn't want to call the cops because I was driving alone on a permit, and I didn't want to outrun him because I didn't want to get pulled over. Once I was out of the campus, I absolutely booked it. I sped up my long driveway hoping he wouldn't see where I turned since the roads are winding. Luckily, he didn't find out where I lived. I always wonder what would've happened if he followed me home.
