There's a sentence in my upcoming book that I've had some doubts about. Should it be this: "Scarcely a month goes by that I don't hear about somebody..." or this? "Scarcely a month goes by when I don't hear about somebody..." I think I've heard it both ways, but I don't know if one form might just be a regional thing, like "different than/different to" or a now archaic form. The first sound more natural to my ears, but that could simply be the way I was brought up. Thoughts?
