Dear Mary | 2 May 2009

Q. I was sitting in a South West train the other day. A woman across the aisle was making nonstop calls into her mobile phone, speaking very loudly in what sounded to me like Cantonese. I found it excruciating. I could not think, I could not read, I could not do anything. I did not want to give up my window seat and move to another carriage. I finally flipped, went over and said, ‘Could you please speak more quietly?’ The woman looked very surprised and quite angry but from then on she spent the rest of the journey texting. I found the incident exhausting. It was 30 minutes or so before it was resolved, so I wondered if there is a way in which it is possible to tip people off — right at the very beginning of their first call — that they are speaking far too loudly?
