I tell the kids in the ballet class who come to the piano, "Don't play, because Mrs Skipp (the teacher) will scold." She doesn't like the kids plinking on the piano because she is usually talking to parents, and the rest of the dance studio is very noisy as there are kids from the previous class, kids for the next class, parents talking to Mrs Skipp, parents and kids asking Michelle and Audrey for ballet equipment, parents fussing over children, the occassional baby cry...
But they continue to plink. They don't even give one look at me. They're not even concerned that Mrs Skipp has scolded them a few times in a row for making a din on the keyboard.
Talk about 耳边风 (literally translates as "the wind that rushes past the ear... the Chinese phrase which means to ignore advice").
