Travelling on a train, sat at a table of four seats. Opposite me was a woman with one of her kids and her other one was next to me. Once next to her was a toddler and the one next to me probably about 6/7.
I was happily sitting there watching a box set on the ipad with head phones in. US drama with bits of violence (guns, shooting, fights etc) and a bit of sex (Homeland for those who know it).
She asked me if I could turn it off as it was unsuitable for her son sitting next to me to watch it. I think he'd been watching the screen and made some comment to his mother from what I could gather when I took my headphones out.
Told her not a chance as it was not my problem.
Then, about 20 minutes left to go, was killing time playing candy crush - again with head phones on.
This time she asked me not to as her kids wanted to play it and she didn't allow it and it would upset them.
At that point I politely suggested she pay more attention to what her kids were doing and less to what I was doing and I'd do what I wanted.
She seemed to think I should modify my behaviour because of her parenting choices.
