Writing guides, grammar books, punctuation how-tos . . . do you read them? Not read them? How many writing books, grammar books, dictionaries–if any–do you have in your library?
I have one!\. Eats. shoots and leaves by Lynne Truss. Having just finished it I can see I should have many more. My grammar is appalling. I'm now spend ages writing my blog debating about semi colons and comma use.
I used to have a dictionary but it got lost on one of out many moves and we never replaced it.
