I Saw Someone I Wanted To Talk To

I was just sitting under a tree resting after work before getting on the train to go home and two girls passed by. I noticed that one of the girls had a disfigurement that looked like her face had been badly burned and scarred. But sometimes I get feeling from people when I see them. Like this person is bad news and I should avoid them, or this person is trying but is making and will keep making many mistakes before they figure things out. Not from every person I see, I think a lot of people are just too "normal" and don't give out any real strong "vibes" or whatever you want to call it. But I picked up that this girl was a really really nice person, the kind of person that makes the people around her better just from knowing her. I wanted to walk up and say something, but I am too shy. I think I should try harder to get up the courage to talk to people if I think it would be a good thing to do.
