Have you ever remembered a stranger forever based on a very brief encounter?

I can think of a couple, below is one of them.

I was waiting at a tram stop, an elderly unkempt woman was standing next to me, she was laden with what looked like everything she owned. We started talking and she told me she voluntarily lived a life, where she could sleep outdoors, have nothing to keep her in one place.  It was winter when I met her, cold and wet, she told me sometimes it was unbearably cold but it did not matter to her.  I was thinking she looked so vulnerable and elderly to be living this life and dangerous.  She had children, she had had a home but walked away from it all.  I am thinking how much truth is in all of this.  Lastly, she told me she had been a concert pianist and she was always welcome to play the grand piano in a high end department store.  At this point our trams came and we went our separate ways.  I thought about her occasionally and I always wondered if what she told me was true, but she seemed so clear and determined in her pursuits.  Our conversation probably only lasted 15 minutes.

One lunch hour I was in the department store and going up the elevator I saw a small group of customers gathered around the grand piano.  It was the elderly unkempt woman I had met at the tram stop, playing magnificently, when she finished the piece everyone erupted into wild applause.

Mmmmm that was kind of wonderful.

In a Malaysian shopping-mall an older ethnic Malay man tried to befriend me and I gave in for a while. Of what I can recall he talked despairingly about the country's Muslim population, contrasted his and my skin colour with a  joking yet serious envy, and showed me a picture of him and some cute Morman missionary girl. I also remember he was Christian, a rarity for his kind. I felt as if though he was genuine, but I was very off-put.

Of other races - those that perceive of themselves with some sort of cultural superiority in comparison to you display themselves on a more respectable footing, a balanced relationship. Christians of the minority races, the totally colonized peoples of this world are extremely servile to the colonizer race. A bit obvious, but its what I concretely got a display of out of the encounter.
