Don't you people sleep? Oh, right, half of you are on the other side of the planet. I see three punctuation errors in this example. (Ow, huh?)
Her eyes didn’t meet his own and her face darkened even more, at this point she was closer to looking sick or sunburned contains two errors.
First is rule number one, the FANBOYS comma for the conjunction and. If you put your finger over the FANBOYS word and you have two complete sentences (independent clauses) on either side of it, then you need a comma before the conjunction.
Her eyes didn’t meet his own[,] and her face darkened even more, at this point she was closer to looking sick or sunburned.
The second error is called a fused sentence, where you have two or more independent clauses joined in a single sentence without so much as a comma separating them (which would be a comma splice). The first sentence ends at the word more, where you need to start a new sentence.
Her eyes didn’t meet his own, and her face darkened even more. At this point she was closer to looking sick or sunburned.
The third error is rule number two, not so much as error as a preference for setting off introductory elements with a comma. As long as it's clear without a comma, the comma is optional. But me, I'd put it in.
Her eyes didn’t meet his own, and her face darkened even more. At this point, she was closer to looking sick or sunburned.
Does each of those make sense to you?
Maryn, decent at this stuff
