I met Mary Ellen Mark at a gallery opening that Hippie Lou dragged me to. I didn't know who she was but she was very friendly and nice to me... Now, in retrospect, I realized her friendliness was natural because she was the kind of person who could talk to anyone anywhere, it was a talent she used to photograph in the streets. She gave me her card, which I still have, and afterwards I researched who she was... How I wish I have asked her more questions about her art but feel very blessed to have had a chance to meet her.

Perhaps that is all you needed to know and learn from her. It seems that little interaction met the purpose
