Forgottenrealmsfan,
Those things Hermione did are exactly the reason why I think Hermione and Harry are only dear friends instead of couples, she treats him like a brother whom she loves very much...
All those things she called Ron, and her arguing with him all the time, shows that shes more concerned with how he's behaving. I don't think she's in love with Ron yet, but I think she will be. Time will tell. :)
