Writing dialogue

On the elevator of a residential building, two middle age woman talking to each other, smiling as if they were true friends:

Mary:

- I can pretend that I’m a nice, normal person while I hold the door for you and say hello with a huge smile on my face.

Jane:

- Well, I can go even further and pretend that I give a damn about your life. In fact, I can even ask how you are doing, while putting my hand on your shoulder, just for you to see how much I care about you.

Mary:

- Alright, I can answer your sick, sarcastic question saying that everything is fine, when I actually feel the urge to attack you and choke you to death right before this elevator reaches my floor.

Jane:

- I can ask you about your son, that drug addict, degenerate bastard, whose car I just scratched with my keys, and even send him my best regards.

Mary:

- I can answer that he is doing very good, when he actually just came out of rehab and got arrested for possession. After that, I can ask about your husband, that horny little hairy beast, who fucked me 3 times on your bed, while you were at work yesterday.

Jane:

- Ok, I can say I am happy for your son, when I truly feel disgusted by him. I could also invite your family to have dinner at my apartment, but I’m honestly thinking about killing my unfaithful husband in his sleep tonight and running away with the dirty money he keeps under the mattress. So…

Mary:

- You know, now that the elevator arrived, I can say that it was good to see you and that we should go out together sometime, when I actually cannot stand being near your awful smell of cheap perfume and all I want is to drop a bomb on your apartment.

Jane:

- I can say that I miss you and you are looking good, when the real thing is, I could pay a million dollars not to see you ever again and you look like the fattest bitch that ever stepped on an elevator.
