Super interesting, Rachy. And you raise some good questions.
I'm with Helena -- I dont mind a clack. I think it was -- yes, Cee! -- my mother's love of 1930s musicals. All those tapping shoes...I love the sound. Anyway, I know I've clacked my way down a few granite floors and corridors and while sometimes I think, well, I'm certainly announcing my presence here, I've never really minded it much. I mean, except if people were trying to write exams or something in the rooms to the side...
Sometimes I think about what roads sounded like in the 19th century. The horses hooves...a different sound than all the engines.
