I don’t remember her name__43__ what her face looked like. I just remember her hands, her voice and the__44__  she taught me.
I can still see her hand __45__  for mine in our introduction. __46__  were so beautiful, I thought; rich, dark skin__47__ complemented(涂了) by the orange colored polish on her nails. Then I __48__ her saying, and not at all in a condescending(居高临下的) __49__ .“Oh no, that is NOT how you shake hands. Let me show you _50___.”
After that, I just remember her voice __51__ the importance of a good handshake, conveying(传递) a positive sense of self, looking at _52___ person in the eye, making that first moment matter…I think in that exchange I first understood__53__.
I respected her for __54__ the time to teach me about one of those subtleties(细微之处) in life. I appreciated the fact __55__  she didn’t look down upon me because I was 11 or because I didn’t know something. And so because of that I felt somewhat respected. I mean the _56___ she treated me. It felt good to be __57__ like a real person. I also appreciate her idea that _58__ someone doesn’t pay attention to something, be patient and point him or her__59__  the right direction. I__60__ her every time I meet someone and shake hands. And I’m so thankful for her little lesson.
