talking during rush hour and the volume at which you do so. Next up: your personal music habits. We realize some people need their music fix to get them pumped up for work, distract them from the drudgery of commuting, or to drown out the obnoxious rush hour talkers. However, we do not to hear each lyric of your music selection. We also don't need to hear the bass beat or your knee tapping against the seat in front of you. While you also may be inclined to dance in your seat, not everyone is up to the task of also interacting with your music. Please confine your music to your own ears. The one earbud in, one out strategy usually means the music spills into the car from the unused earbud. This in turn may make a fellow music listener turn up their own music, which causes another to turn up theirs, until a wave of loud music listeners takes over the train. Your music collection may be the best there is, but your fellow riders will be much more pleasant if they are not forced to be educated in your musical genius.
