How Long Do You Let It Go

How long do you let a co-worker go around with a potato chip in their nose? Probably depends on how she has treated you and how much you like her I suppose. Seriously, do you let it go on for a couple of minutes or a week or two or three? What if she had been nasty to you in particular, do you let it fall steadily to her knee? What if she is your best friend, and you see it hanging out of her left nostril? What do you do? For goodness sakes, Rosemary, you are wearing a potato chip in Nostril Number Two!
