You’ll want your dialogues — whatever they are — to be easily read. Hence, I suggest using a brief “settings” intro, and italics, and punctuation in any clear and consistent format. Remember how we began in class?:

Example 1:

7AM. At the Church Avenue F and G trains stations. There are a bunch of upset people late for work or school. Man in suit keeps checking his watch and looking down the tunnel for the train coming.

Man That Can’t Keep His Pants Up: “Where the &*(%)%* is the train?”

Woman In Red Sitting Two Seats Down From Me [staring at me, writing.

Group of children running down to the other side of the platform.

There is a train arriving. Everyone gets up as I stay seated. The green reflection of the trains shows that it was a G Train. Everyone returns to their positions, upset.

Man That Can’t Keep His Pants Up: “Oh my ^&^&^E god, where is this $%($%$ train?!” (He yells as if it will make the train come faster.)

Surprisingly, the train is now arriving. Man in the Suit rushes to the door in the exact spot where the door will open.

etc etc.

Example 2:

7 Train. 7:40PM. A man of around 19 is standing, holding the pole. He talks to another man who appears to be his friend.

First Guy:             I broke up with my girlfriend. She flirted with other guys. Basically, cheating on me. I wasted six months with her, and this is what I got.

Second Guy:      Damn, I feel bad for you. Wasn’t she your first girlfriend?

etc. etc.

Example 3, modified text:

7 Train. 7:40PM. A man of around 19 is standing, holding the pole. He talks to another man who appears to be his friend.

“Only wanted a girlfriend to just have.”

“You picked wrong.”

Gosh, these people are having a tough day. I wish I didn’t have to sit here.

“Why did you even go out with her?”

I wonder what he’s going to say now. Oh no.

“Man, you always choose the wrong girl.”

etc etc.

Another example. An easy and sort of classic use of italics and quotes. Example #4:

Midnight. Starbucks on Madison Avenue and 57^th Street, Manhattan.

I wish I’d never left the house. No one is sitting near me, but there are a number of people at the other end of the room. Man, it’s pretty empty. I feel kind of self conscious, writing in the corner. I am drinking tea.

“Hi, could I get a macchiato?”

“Vente or grande?”

“Vente”

Why can I hear the people at the counter, even though I’m so far away? I wonder….

[Music. “Uptown Funk.” Again?!] “Julio, get the stretch!”

“Um, I asked for a vente and this is a grande. Can you please get my order right?”

Wow, this woman is picky. Why is she even ordering a coffee at midnight anyway; doesn’t she ever want to sleep? My herbal tea is getting cold.

“We show up when we show up – smoother than a fresh jar o skippy…”

“Here’s your change.”

“Um, okay.”
