Number 3 - My first stranger of the day, but the rest were all in a queue ready to go into a Convention so don't really count.
Lissie was on her way to the convention, but I spotted her coming of the top of an escalator and just had to ask.
Now my take-away from this "Stranger" - when indoors check your exposure and ISO. I needed more ISO for the environment to overcome camera shake... only noticed when I got home. https://www.youtube.com/watch?v=ojYK6CW8gdw&list=PLD8D210249478A9A5
