Oh, WW, i am so glad you are OK-- and i wonder if your turning round, facing the person, and interacting with him didn't change the situation. you went from being persued, to taking charge. you saw him, and you didn't confont him, but you did make a statement. i suspect if he had a knife out, he was planning at the least to rob, if not to sexually assault you. and instead, you acted, and your actions changed the situation-- and as scary as it was, i hope you see that. I hope what you have taken away ifrom the experience is courage, and not fear.
