Now......I could well be shot down on this as I haven't been to school since the early eighties but what is peeing me off is the increased use of a comma and the word "and" in a sentence, either before or after each other:
"We will see how it goes, and decide then "
...when (I think) use one or the other but not both, like that anyway.
I see it in emails at work and even on TV or in the press...and don't even get me started on "effect" and "affect" !
