My least favorite thing is being around when somebody has to discipline their child. To me, it's bad parenting to have raised your children in such a way that they would act out so much, and need to be disciplined physically in a public place.
Right now, there's a mother and her child who have made their way to the bottom level of the coach, him bawling all the way there, and her pushing and pulling him in order to take him away from general view. I can still hear them, and she is spanking him, and he has not stopped screaming and bawling. I have heard "I don't" or "I want to" but I'm still not certain what's happening.
I think it may be that he doesn't want to be on the train, but I'm not sure. My brother has informed me that it may be because he needs to use the restroom, and the mother is telling him to stop being mean. I'm not sure if that's what it is, but I am continuing to acknowledge that it's a very awkward situation.
If-slash-when I ever have children, I'm going to try to raise them in such a way that this doesn't happen. It's obviously not too hard, because dozens of other families I've observed this trip have not had any such problems. Their children were normal children of course, but they have all been mindful of the fact that the train, while bigger than a bus, is a small place, so small indoor voices should be used. (Also: there were generally no tantrums.)
