My sons both crack their fingers, toes, neck, back. They know the sound absolutely grates on me but they continue to do it if though I ask them politely not to. They argue it’s the same as asking them not to scratch an itch. They even click their fingers to try and then tell me it’s not them cracking their fingers and its driving me nuts.
My eldest hates the sound of polystyrene and I went out of my way not to annoy him when putting away the decorations but he won’t afford me the same courtesy. I’ve a lot going on at the moment so might be being over sensitive.
AIBU.
