The manicurist knows that I am sensitive to sound, and usually wear my earbuds to listen to loud music so I don't have to listen to the customers in adjacent spaces having their nails filed or callouses buffed off. Although the buffing of my feet can be somewhat ticklish at times, this time when she was filing my nails it struck me how I wasn't bothered by the rasping sound. It then occurred to me that maybe what bothered me about hearing other people's nails being filed wasn't just the sound of the filing, but the fact that I wasn't FEELING the filing at the same time as the sound. Perhaps part of my annoyance of sound triggers when other people do them is that since my other senses don't experience the sound too, the body is discomforted by the disconnect between experiencing one sensation but not feeling the corresponding sensations that go with it...
Something for me to ponder as my journey for relief continues...
