1. Don’t find it unique, it’s prevalent in many cities. Melbourne CBD just has it to an excessive level.
2. Tell them you don’t like it. Ask the parents to shut up their kids. Teach your own children to be more polite and respectful on public transport & in general.
3. I wish I knew why. My daughter was on a 3 hour call organising outfits yesterday. At least she put the call on her headphones while we were in the market.

I think there is a fear of upsetting children so rarely parents are told that their children’s behaviour is disrespectful and disruptive. PT is for all not just the bogan’s.
