She may have meant for you to put your undergotchies in with hers - thats what mine wanted - i was soooo grossed out. She was washing everything in one load and with cold water and no bleach - stuff was coming out chunky. At least when i lived with her i made sure things got separated and clean. She complained the bleach wore out the elastic on her undies. I didnt care as long as they came out bright white.
