Just remembering, ... Stanley Ann Dunham was an au pair/ nanny in Chicago, so she was already experienced, - oh! double entendre not intended.
I have not seen any source other than Dreams, written by Ayers/Obama, for the claim that Stanley Ann was an Au Pair in Chicago.
Since FReeper detectives have apparently shown that “Black Orpheus” did not come out until Dec 1959, SAD would have been 17 during the summer between HS and U. of HI.
Ayers seems to have used the Black Orpheus episode to further his own black/white racial narratives.
