Currently on a long distance train journey, fairly empty coach. Across from the aisle there's this woman who is painting her nails. I loathe the smell. Now, I realise this is a minor annoyance, and that I can move to another empty seat, but just for the sake of passing the remaining 3 hours on my journey: AIBU to think that personal grooming (nail painting, applying full face of makeup, extensive hair brushing etc.) is best reserved for behind closed doors?
