She was born in in September 1960. I was born in January, and started Kindergarten at age 4, in September 1964. My HS graduation was 1977; she would have started a year later, and the records I have show that she had been held back a year, and so it made sense that she was part of the class of 1979. But she also dropped out (May 1977) at the end of her Sophomore year. She would have been 16 at that point.
This is relevant to some of the history that I will relate, and it all helps confirm my timeline.
