Nothing. What should I react to? And why? Women are entitled to walk around by themselves. They are adults fool.
I am sad for them.
why would you want to see people alone ?
Why didn't I marry that one instead?
Not sure if I have any reaction... most likely she would just blend into the tens of thousands of other people that had crossed my peripheral that day. Is she attractive, smiling at me, doing something to get attention, projecting that she is approachable? Those are things that are more likely going to allow me to form an impression.
why react? it's none of my business
A great deal of respect and happiness for her
I likely wouldn't have one.
