I sat behind a woman on the train home yesterday. Her music was turned up too loud which was a bit irritating especially as it was Celine Dion, MHWGO. Then when the song finished, she listened to it again... and again. In the end I heard that bloody song 11 times before I got off the train. And it was LOUD enough to hear every word.
Also, at one point, she began to quite loudly floss her teeth. AIBU to think that's really quite odd?
