" You get a stain on your pants. Your favorite pair of pants. You wash them ten times in a row at 160 degrees. You scrub and scour and rub. You bring in the heavy artillery. Bleaches. Abrasive cleaners. But the spot doesn’t go away. If you scrub and scour too long, it will only be replaced by something else. By a stretch of fabric that is thinner and paler. The paler cloth is the memory. The memory of the spot. Now there are two things you can do. You can throw the pants away, or you can walk around for the rest of your life with the memory of the stain. But the paler cloth reminds you of more than just the stain. It also reminds you of when the pants were still clean. "
