This is just wrong.
And I don't really blame the teen mom, who actually was already onboard the CTA Red Line train before the middle-aged guy got on and blocked the rest of the aisle with his rolling suitcase.
Of course, the teen mom could have sat on the other side of the doorway, and parked her monster stroller in the ample space there for wheelchairs.
And of course, the middle-aged man could have slid his bag in the space between his seat and the back of the adjacent seat.
Instead, we have a mammoth roadblock that tripped up at least three people.
Can we have a little courtesy, please, people?
