Encouraged by having just received a sound, if second-hand, telling off for a deliberate grammatical faux-pas in an email, (the offended person feeling safer in sending her good husband to do the dirty deed) I have decided to form a new organisation for the sort of person who might read (and enjoy) "Eats shoots and Leaves".
However, being of a perverse nature, Ill have to give it an inappropriate name. Thus I commend to you:
The Society for the Prevention of Cruelty to Apostrophe's.
My Malicious and cruel imagination can see English teachers exploding up and down the country even as I type.
