Sure can! I must admit I can spot a spelling or punctuation mistake a mile off but my real bête-noir is the misuse of the apostrophe in the word "its" because it only needs a second or two of thought to get it right. I must have gone through my booklet on Cockersand Abbey innumerable times to get it as I want i.e. spelling, punctuation, grammar, spacings etc, but I always find something just after I've printed out 24 copies!
