This person did not confront the mother at the time but decided it was appropriate to have a whinge to the local paper afterwards.
The mother probably had no choice but to catch the train and ‘old-fashioned’ disciplining doesn’t really exist anymore since it’s unacceptable to spank our children with a leather belt these days.
Being that the mother was also stuck on the train meant she couldn’t just remove them from the situation and give them time out either.
There is a difference between a noisy set of headphones and a noisy toddler, hence why the sign doesn’t say keep your child quiet.
People need to be more tolerant and sympathetic or not catch the train themselves.
