I'm on a train. The guy behind me is watching some kind of sports match on a tablet. I travel a lot by train and often, mostly at the weekends, there are people with gadgets that play films or TV and they don't put their earphones in. Slightly separate issue from having the earphones up too loud - that's annoying but a part of life, however to not even try to mute the noise by just playing your TV show to the whole carriage? Fuming.
When I was 19 (and too shy to turn around and politely ask someone to keep it down) I had to endure Dora the Explorer at full volume from Penzance to London whilst the child's parents read their own book.
AIBU? Is it acceptable not to put earphones in? Am I missing a trick?
