My Doppelgaenger in San Francisco (1)

I'd really appreciate if you'd take some time to read this writing, correct it,
or give me any suggestions or better and natural expressions. Thank you.

My friend and I were chatting as we were walking down one of the long slopes of Chinatown in San Francisco. It was our first visit and we were total strangers there.

We noticed a young woman, who was at the far corner of the block below, she started to call out a name loudly in the direction we were coming, “Nancy! Hey! Nancy!” She was smiling very happily. I wondered why nobody on the street between us and her was replying.  All the people around her were looking at her strangely. So I looked back to see if the person “Nancy” was there, but I couldn’t find anyone as to who it might be. I heard my friend asking me suspiciously, “Do you know her?” “Why? No way!” I answered and found the woman was now running up to us and still calling for Nancy. And, she was gazing at me!
