Okay. So my grammar checking soft ware keeps saying something. I wonder if it is right or if it is wrong. And hopefully in either case maybe understanding it. Many times I am finding myself using the word "though". Generally like this. The woman wasn't that concerned though, being late wasn't the end of the world. or Her eyes could see it clearly though. The grammar process seems to think that every time I use the word "though" that it needs a comma before the word. It gives this as a reason. It appears that you are missing a comma or two with the interrupter though. Consider adding the comma(s). Adding a comma before though seems awakrd in the above examples. Second issue. Looking inside, she saw Victoria's shadow and raced to keep it in her sight. When the comma is removed it labels this as a sentence fragment. Why? Thank you.
