1. At the station. A woman carefully goes through every page of the giveaway magazine "Sport" to make sure there's nothing in that will traumatise her nine-year old boy. Meanwhile he waits patiently and looks up at her expectantly.
2. On the platform. A woman with a seven year old boy who's wearing one of those anti-pollution face masks.
3. On the train. A woman with a well-dressed two year old boy. He turns to look out of the window and puts one of his feet on the seat. She immediately smacks him once on the backside. He starts crying, more out of shock and embarrassment than pain. She lectures him in some East European language for about ten seconds and then tries to cuddle him into submission. He, being male, is immediately placated. So she gives him a Milky Way.
