Many of my more vivid memories are brief encounters. I don't keep my shields up very well, and people talk to me.
I was picking up fruit in the supermarket when an elderly lady asked me a question about the oranges. The conversation quickly moved to more personal matters, face to face across a bin of oranges.
Suddenly she burst out, "How come a complete stranger cares more for me than my own family?"
I don't know what I said in response. I hope I was smart enough to keep my mouth shut.
