I had my monthly steak dinner with my friends at 730, so I decided to go to the coffee shop next to the restaurant at 5 and get some reading and work done. I sit down and there's probably 10 people in the place, half of them studying and doing work. For the first hour, everything is fine. I'm now reading and I notice this 25ish year old kid sit at the table next to me. No big deal, I keep reading. A minute later, I hear his music, and it's quite loud and clear that he's not listening on headphones. I assume he's a decent human being and that it will stop, but I can't concentrate. So, I put my book down and watch. The song ends and then be moves on to the next song. It's now apparent that he is going to be listening to his music, for all to hear, until he leaves (and, who knows how long until that happens). I probably spend at least 6 hours a week in various coffee shops, and this behavior is novel and aberrant. I look at this kid and it's pretty clear that he is not suffering from any mental disorder, he's simply inconsiderate.
TRUT: Excuse me.
Kid: Huh?
TRUT: Have you ever thought that what you are doing might be annoying to others?
Kid: What?!?
TRUT: Have you ever considered the possibility that other people might be around you and might be distracted and annoyed by your music?
Kid: No, bro.
TRUT: Well, you should consider that, because it is annoying.
The kid glares at me, but turns his phone off. So, I return to my book and keep reading. Meanwhile, I can hear the kid fidgeting in his chair and huffing. I keep reading. Fifteen minutes pass.
Kid: Yo man, that was a bold ****ing move.
TRUT: So it was.
Kid: You're an *******.
TRUT: So I am.
Kid: Listen dude, you can't just go around running your mouth and talking **** to people.
TRUT: I will say what I want to whoever I want.
Kid: Well, well, you don't know anything about me.
TRUT: I don't need to know anything about you.
Kid: But, but, you don't know who I am. Like, you could have just said the wrong thing to the wrong person.
TRUT: Are you that wrong person?
Kid: What?
TRUT: Are you going to do something about it?
Kid: Well, no, but, look man, if you run your mouth to everyone. I'm saying, that you don't know about them, and...
TRUT: And, what?
Kid: They could, I don't know, they might, they...
TRUT: I'm just going to stop you right there. I've been to Ranger School and I've been shot at in Iraq, buddy. There are few things left that scare me, and you're certainly not one of those things. I suggest you either shut the **** up, leave, or take a swing. We're done here.
At this, the kid grabbed his **** and left. There was an early 40s black couple a few tables over, and the guy just started laughing his ass off.
Moral of the story: when you're in public, if you can't deal with someone else letting you know that you are an annoying little ****, then don't be an annoying little ****.
