Why Was She Crying?

It's amazing that you can read the Bible over and over and over again, and suddenly realize, that it appears someone slipped something in that wasn't there before. I've been reading in Luke's gospel, and it appears that he slipped something in his account that I have overlooked. The 'sinful' woman who anointed the feet of Jesus, approached him from behind. Luke records "and stood at His feet behind Him weeping...." Luke 7:38 She had heard that Jesus was there, and so she arrives with a gift of fragrant oil, and stands behind him weeping. Weeping in the presence of Jesus, bring a gift, and bowing down behind him. I know that she has always been wiping his feet with her hair, and washing them with her tears, but it has never occurred to me to question why she was crying. Luke is silent about this. However, she does leave forgiven. It doesn't appear that she is asking for forgiveness, but nevertheless, this intimate encounter with the feet of Jesus is transformational for all. Jesus says that what she has done will not be forgotten. Ever. Yet I wonder why she was crying. Probably the best place to cry is at the feet of Jesus. He can make it all better.
