From Eats, Shoots & Leaves by Lynne Truss

From the preface

Grammatical sticklers are the worst people for finding common cause because it is in their nature (obviously) to pick holes in everyone, even their best friends. Honestly, what an annoying bunch of people.

...

Standards of punctuation in general in the UK are indeed approaching the point of illiteracy; self-justified philistines ("Get a life!") are truly in the driving seat of our culture; and a lot of well-educated sensitive people really have been weeping friendlessly in caves for the past few years praying for someone--anyone--to write a book about punctuation with a panda on the cover.

...

Some may say that the British are obsessed with class difference and that knowing your apostrophes is a way of belittling the uneducated. To which accusation, I say (mainly), "Pah!" How can it be a matter of class difference when ignorance is universal? Why should it only be middle-class people who care about the language? ... Punctuation is no more a class issue than the air we breathe. Caring about matters of language is unfortunately generally associate with small-minded people, but that doesn't make it a small issue.
