I really enjoyed this, an old lady takes a walk around New York and her old haunts, talks about the good and bad of her life. 
She is a lady who went against the status quo and lived the bohemian life with a job in advertising which she loved but her parents did not approve of, and in a time when all there was for women was the marital bed and children. She became the highest paid advertising woman in the industry for Macy's. 

She suffers with mental health and the struggles of eventually falling in love and having a baby which meant the loss of her beloved job. 

Sentimental, perhaps but I enjoyed this a lot.
