so I took the train recently. and now my back hurts. WHY? because the designer of said train decided that clearly no one would want to sleep on a train unless they paid the extra money for a sleeper car. oh how wrong. and just like in so many airports who created rows of chairs that are impossible to lie down on or even get comfortable in, they decided to build an hard metal pointy arm rest that, even though the train was half empty and I had two seats to myself, made it impossible to curl up and sleep.
