Yup...good/bad story. I've had a similar (s) story with the wash.
I had just started a new job. Written down in my handy dandy pocket notebook ALL the codes/passwords and helpful hints I had learned that week. Per usual, on the week end, I washed my lab coat. Needless to say when I opened the dryer there was this obvious poof of fluffy white material...piles of it! I've been known to wash an ink pen or two, or many, through the years. With my white lab coat, of course.
My kids once washed red clothes with my underwear. Had pink underwear till I went store to replace.
