I've been told by an editor that the phrase below has tense issues but I can't see it myself...perhaps because I am not a grammar whizz. Comments that would be helpful are much appreciated. I favour running in such situations and, thankfully, J.B. feels the same. P.S. in case you are wondering why I am not asking the editor directly - I don't want to look like a chump.
Other than a misplaced comma, it looks okay to me. As Lightman pointed out, we are seeing it out of context. But for that sentence in isolation, there is nothing wrong with the tense. "I favour, and J.B. feels." Running is a gerund, and is just fine as well in its context. That accounts for all three verbs.
I don't think there's even a misplaced comma. "Thankfully" is parenthetical, so it correctly has a comma before and after. And nowadays linguists would say that "running" is a "naked -ing form" so it may or may not be a verb, but that doesn't change your analysis. If there's a problem it's in the relationship to what's around it.
There's nothing wrong with it. What comes before and after the sentence? Perhaps your editor meant that in the context of the paragraph, it doesn't work, rather than the sentence as a stand-alone?
i agree there's nothing wrong with it... the editor isn't a very good one if he thinks there is... cog, why did you think a comma was 'misplaced'?... i often have to correct mentees and clients who place the one used after 'and' here, in front of it, in similar cases... which is incorrect, as the parenthetical is 'thankfully' not 'and thankfully'...
At first glance, I thought the coma was not needed, but rereading it, it fits. Its dialog so perfect sentences aren't necessary. Basically wouldn't; "I favour running, thankfully, JB feels the same." says pretty much the same thing. This sentence shows MS WORD 2007 isn't great to trust: no comas at all, one comma after thankfully, both comma's are all accepted without flags. The only flag was the english spelling off favor.
Ah, then I think I now understand the editor's point. I believe that it is a change in tense to the overall story tense. I can't really post any more here without posting too much and it is in re-writing / resubmitting stage. The editor's comment was just a bit vague I think.
