This little story I’m about to tell you happened when I was 11 years old, and I’ll never forget it.
It was at my friend Jenny’s house after 36 one day, and we were doing our homework. While I was there, a friend of Jenny’s mom came over to 37. I didn’t know her name or 38 what her face looked like. I just 39 her hands, her voice and the lesson I 40 from her.
I can’t forget that she 41 her hands to introduce herself. It was so 42, I thought, rich fine skin; then I heard her saying, “Oh no, that is not 43 you shake hands. Let me teach you.” She didn’t do that at all in a condescending (屈尊的) manner. 44 that, I just remember her voice explaining the 45 of a good handshake of conveying (传达) a   46 sense of self-belief, of looking the other person in the eyes, and of making a warm  47. Hearing her friendly words, I first understand what being 48 meant.
I admired her for 49 time to teach me about one of the important things in life. I was grateful for her not talking down to me 50 I was 11 and didn’t know much. I also felt somewhat admired by the way she 51 me. It felt good to be talked to as a(n) 52, rather than as an 11-year-old child. I also 53 her telling me that if someone isn’t aware of something you should show him or her the right direction; don’t be afraid to 54 your knowledge.
I think of her every time I meet someone 55, and I’m so thankful for her little lesson.
