I only have two girls, so I don't know the ins and outs of parenting boys. Sometimes I am surprised at the height and age of boys being steered into the "ladies" room by their mothers. Often with Fathers waiting outside!!! (Lazy gits.) I am thinking that in a place like a train station you should expect to see mum's being fairly protective, but I get a bit annoyed in places like National Trust toilets, when the boys seem embarrassed/interested.
What's the proper etiquette?
