Sister, I was walking home from work today....I was full of that horrible free floating anxiety...couldn't work out why....just felt like I was about to be attacked...I noticed this guy walking toward me and thought nothing of it...I crossed the rd and then out of the corner of my eye I saw the same guy walking behind me...I could see something in his hands and thought he had a knife...I stopped and pulled out my phone to pretend to use it and allowed the guy to walk ahead of me...I kept looking at his hands and then saw he had 2 cell phones and one of them rang and he started talking...I realised then that he most proberbly had changed direction because he had recieved a call or something...I crossed over and kept my eye on him until I was convinced I wasn't in his awareness like he was mine :-(

Its hard, but its good to be vigilant! you did the right thing!
