['I was on my drive home from work today and this guy started following me.  It was kind of scary', 'oh my goodness. what did you do? are you alright?', 'I was worried he was going to follow me home.  eventually he went a different way.  but it was scary']
i would have pulled into a public place or police station. i'm so sorry that happened to you but glad you are ok.
I was driving and this guy started following no matter which turn i took.  I was worried that he was going to follow me home
