There are some genuinely hilarious moments, and I had to stifle laughter several times on the train. My favourite moments includes Bridget's Freudian slip when referring to her screenplay 'The Leaves in his Hair' as 'the nits in his hair' while texting her toy-boy under the table in important meeting re: her children possibly having nits. There are also some sad parts, not least Bridget's memories of Mark Darcy, but the most sentimental part I felt was at the end. Bridget's father has passed away, and her mother, as full of life as ever, is living in a retirement home with her best friend, also a widow. Bridget and her mother have a similar relationship to the previous two books, but only at the end of the book do we see Bridget and her mother reconcile and tell each other how they really feel.
It is interesting to think about what the reception would have been to this book had it been Fielding's first Bridget novel. Readers are inclined to give 50 year old Bridget a pass with regard to her thoughts and behaviour, as we already know Bridget from her adventures in her 30s and have prior affection for her. However, 50 year old Bridget, taken as an independent entity, can come off as incredibly privileged, immature and spoilt. She lives in a good part of London, has zero financial worries and hardly any responsibilities, she has enough money that she doesn't need to work, has a nanny and a cleaner, a group of supportive close friends, and children at a fee paying school. For many (most) of us in terms of finances, she's living the dream- yet remains, as ever, "mad about the boy".
Overall, despite the book and Bridget's faults, my enjoyment of the book came down to the nostalgic pleasure of spending time with an old friend, and one who makes you laugh, at that. I think this book would make a good gift for those who were fans of Bridget's previous diaries, and I would give the book a 3/5.
