Real civil conversation I heard on the bus going home last Friday.
Old man talking to two guys sitting behind him: "You're making me nervous. Hey driver, these two guys are saying something to each other in Arabic. I don't care what the fuck you're saying, you're making me nervous. I don't care if you're fucking talking about sports, you're making me nervous."
Old lady standing about 15 feet behind the old man: "Okay, pal, you need to take it down a notch. That's enough."
Man: "Yeah, let's just wait until they blow up the bus."
Woman: "I hope they start with you first."
Man: "They want to start with me first, cause I'm Jewish."
Woman: "You should be so lucky."
The Arabic men were silent throughout this situation. The old man shut up after the woman's last line. All I have to add is, in another city, or in this city on another bus, I could easily see a different reaction from the others on the bus, one where they justify the old man's fear and also complain to the driver about being "nervous." It could have turned into a really ugly situation, well, uglier than it already was. You know what I'm nervous about? All the dumbasses in the world that feel like that old man. That really makes me nervous.
