To the young lady on my train last night,
I know you were confused about the pole in the middle of the train car. I just wanted to let you know that the purpose of the pole is for people (sometimes multiple people) to hold onto it while the train is moving.
I'm pretty sure the train's designers did not put it there for you to practice your stripper routine.
Just thought you'd like to know.
p.s. It's autumn now and it's starting to get chilly. You might want to invest in a sweater or something.
