A Frayed Knot!
Today I decided to address an issue I've had for ten years! It involved a pair of shorts. With a ten-year-old knot in the waistband pull-string. Sometime in the past I made a knot in the string after pulling the shorts snug around my waist. For the past several years, however, the shorts have been loose-fitting. Apparently, I lost weight. I tried to dislodge the old knot over the years with no success. No tool I tried ever worked on...
