this title is not a promise I want to have from my friend. this is a bestseller written by Sophie Kinsella——a brithsh writer.I love this book which is very interesting and humour.I believe everyone have a few secrets.Not the big secrets like who will be next president,but very private ones.However what will happen when some one know your secrets,and thing happened as what you have said...I'v know idea but I know when people know my secrets ,things will be different...Sometimes I prefer no secrets with people.I'd like to make friends with honesty.when I stay with friends I'd like to show who I am.
