Refined people such as you and I can continue to wonder whether I put too many commas (or not enough) in my last sentence, whether 'combines' in that sentence would be acceptable, or whether we can tolerate 'me' in place of the italicised I in the first line of this sentence - or whether this sentence is too long and/or whether the '-' is an acceptable punctuation mark.
