Hi Custardo, Ok, along those lines then I'd thoroughly recommend:
My Life on a Plate by India Knight: About a London mum who drives her child to school in her pyjamas etc, suspects she may be a crap mother, has relationship problems, gets over them. This book made me laugh a lot. Ditto 3 friends who agreed.
The Best a Man Can Get by John O'Farrell. Someone else said, and I agree, that it contains one of the funniest descriptions of being woken up in the middle of the night by children ever written.
Having it and Eating it by Sabine Durrant. Woman with two children, mid thirties crisis. Funny, sad in parts. Not as good as the 2 above IMO, but still worth reading.
If you like Jilly Cooper, I've just read Pandora, her new novel and loved it because it's very Jilly Cooper and I've been a fan for years. As The Observer said, the plots of her novels are basically all the same but you forgive her since she does what she does very well.
How to lose friends and alienate people by Toby Young. How he went to New York to work for Vanity Fair and failed miserably to win friends and influence people. He comes across as a complete w*** but I was still riveted by the book.
Notes from a small island by Bill Bryson. American travel writer takes a last tour around the UK before moving back to the States after 15 years in England. Witty, affectionate and accurate descriptions of the English and our mannerisms and mores. I sent it to my mum who said she laughed so much she farted! Not a very my mum thing to say at all.
High Fidelity by Nick Hornby. But the film was very faithful to the book so maybe don't bother if you've seen the film. Nick Hornby said of the book (I paraphrase): "I hope it makes women realise that they should stop despising men and feel pity for them instead" North London man refuses to grow up and leads a life dominated by lists - top 5 ex girlfriends, b sides, songs about death etc.
Anita and Me by Meera Syal. Indian girl grows up in Midlands. Better than Life isn't all ha ha hee hee IMHO.
HTH. Would love to know what you end up with and what you thought.
