Bike seat

entering the orange line at north station through oak grove, 12 minutes long (according to the website of oak grove village), i wondered why this guy held his bike like this, his front wheel on a seat. it was not that he was stuck or something, because he also just left at oak grove station. maybe he just thought his bike deserved a seat? he didnt think his bike deserved the escalator, instead he carried it up the stairs.
right now it is 11 in the evening, and still almost 30 degrees and very humid. sleeping will be difficult once again....
