Just this weekend I learned that my friend Kathy (with a K), who had been rushed to the hospital because of an appendix attack, was recovering from something much more serious.  

Initially she thought it was only really bad menstrual cramps, which wasn't unusual for her. She learned the truth of the offending appendix at the ER when the pain got too intense. Off she went into surgery. She'd have a quick appendectomy and be set!
