On From A Simple Mind, Cis writes of getting new hearing aids: "On the way out of the (Costco) parking lot, I heard this kind of squishing sound. Then it dawn on me, it was the tires rolling on the pavement. And I have since learn that my dryer makes a scrapping sound as well as the hum of the motor. And when I turn on the television, I had to run to the remote and turn it down, as it was so loud from when I had been watching it earlier in the day. These keys are noisy as well. And I laughed as the King turn on the turn signal and I thought about how noisy it is, and it sounded weird, as I realize I could hear it well now. Oh, yea, I ran into the kitchen to find out where the water leak was, as I could hear water running... only to find out it was the dishwasher... funny I never heard that before. More here.
