Some Personal Space Please
There are all kinds of people riding the tube. Most of them are strangers to you, so you avoid talking to anyone or asking anyone anything, because you’re not sure how the person will respond. Will they be nice and friendly, or unpleasant and rude? This woman was clearly very annoyed, but decided not to take a chance.
She lost all of her leg space when the person sitting across from her decided to stretch their legs out so far that their sneakers were practically rubbing up against the poor woman. However, she probably did the right thing by not saying anything. If someone’s actions are this rude, imagine what their words would sound like.
