Unnecessary irritation?

On dn.se, a Swedish news site, there's a woman who writes about code of conduct and anything related to behavior toward others. People can write in and ask questions or just comment on issues that they've been thinking about. Now this one girl wrote in, complaining about having to put up with another woman putting on makeup on the train. According to her this was public space, and such things as putting on makeup should strictly be done in the private sphere of your own house (or possibly a public restroom). I don't understand this problem. What harm could putting on some makeup possibly do? I much prefer this to people eating smelly food or with their mouths open, or people listening to loud music or talking too loudly on the phone. But applying some makeup, unless the woman spilled her powder all over me, would not bother me the slightest. I probably wouldn't do it myself, I look too horrendous to be seen in public before I've put on my mask, and I also think I'd feel a little uncomfortable being stared at while applying my makeup. Not to mention the general bumpiness that you have to endure on a train or a bus, I have a hard enough time getting an even result when the surface I'm standing on isn't moving!

I think people need to find better things to worry about, than if someone who was perhaps running a bit late was putting on makeup on a train.
