That, really.
I make a point of sitting in the quiet coach, where available in order to be able to work, read or just be alone with my own thoughts.
Today I'm joined by a young family with a baby. Of course, the baby starts crying whenever we go through a tunnel. Arrrgh! I know children make noice, hence KEEP.THEM.OUT.OF.THE.QUIET.ZONE.
AIBU?
