Smelly feet
Putting your bare feet up on the seat of a train carriage is bad enough, as we’ve seen. Doing it at a baseball game so that they are right next to the face of the little girl sat in front of you is even worse. This takes a complete lack of empathy, as she’s not at all bothered about the effect her position is having on those around her.
Sure, her feet might not be that smelly, but you wouldn’t want to sit in your front room watching the game while seeing some stranger’s feet out of the corner of your eye, would you? Maye put some shoes on? Or just keep all of your body parts to your assigned seating?
