On a train journey that’s around 2.5hrs, start to finish. Family with three kids behind me who are simultaneously using devices to play lots of music and games out loud - including the Dad, who is actively showing noisy videos to a disinterested child! Mum is ignoring all the kids despite them turning the sound up constantly.
AIBU to think it is crap parenting to let your kids disturb everyone else and it teaches them that their wants always trump everyone else’s??
