I love this story, but I think you definitely rushed the ending. There were more spelling and grammar mistakes than usual and it was really brief. Still good writing, though, and I like the ending.
Ah! Scary! But you know the first rule of having a car following you is to NOT go home! You're supposed to go to a police station or a place with a lot of people that you can yell to. Anyway, please update again! I was so psyched to see your title in my e-mail!
