I was about to post the exact words..."mixed feelings" , "prolonging poverty",as juliaa used. And that Frankie thought she might be enabling the people that she was working with to stay dependent and not develop their on self-sufficiency. Juliaa, who posted right ahead of me, and I seem to have the same thoughts on this.
Frankie wasn't clear on her own feelings about her work in Africa, yet probably felt that people thought she was there for all the right reasons. Frankie's thoughts were mixed with feelings for the people, doubts about her work. Also, Frankie mentioned in the very beginning of the book that after she had been home awhile she would wonder whether being in Africa was an attempt to be away from her Mother. Whether that was the point of Africa for her. She had many doubts thoughtout the book, but she did have a strong pull towards the work in Africa as well.
