Putting make up on a train, is that just paint?  Ha ha.  I don't want to make too big a deal about this because it is a different culture and it would be difficult to get the full gist without knowing too much about it.  With that said, it's is pretty worrisome, in this country as well, how much people are telling everyone what they should and shouldn't be doing.  Live and let live is still the best way to go about things and comparing putting on make up on a train to pooping on the train is pretty ridiculous by any standard.
