Bidoof, if it was meant to be a joke the best thing to do isn't to tell the person it was aimed at "There's something wrong with you " if they didn't take it as a joke. Some people have a hard time taking sarcasm. ESPECIALLY when it's in writing. The best thing to do is to apologize for the misunderstanding and then say it was just a joke.
Nicole really didn't do anything wrong, so Please, do not start a fight with her.
EDIT: Also, bidoof, some people don't like to edit now that Jeremy, or whoever it was made it so you don't receive bells from editing your post.
