Don't own Fullmetal.
Colonel Mustang is sitting behind his desk, going through some papers. Major Edward enters the room and flops down on the couch in front of the desk.
Colonel: You look like shit.
Major: Piss off.
Colonel: What, date not pan out?
Major: You would know. You were watching.
Colonel: Only the first half hour. I left after the food was served.
Major: Oh?
Colonel: Usually nothing much happens after that, at least with virgins like you.
Major: Just because I (Colonel gives him a teasing look) Never mind.
Characters pause. Colonel signs a few of the papers on his desk, Major takes out a notebook and begins writing.
It's not going to work out, you know.
Colonel: Oh?
Major: She's a lieutenant.
Colonel: So?
Major: So, no dating someone below your rank.
Colonel: Oh.
Characters pause. A few more papers are signed, Colonel looks back up.
Wasn't that pretty anyway.
Major grunts and walks up to the desk.
Major: Here's the report on the construction work on the new Research building. Puts paper on desk, begins to walk away.
Colonel: You know I could set you up with someone else. There are a few in your rank.
Major: (laughs) No thanks. But I'll get your advice on restaurants again when I do find someone. Leaves.

Try acting it out, if you want, and take all the liberties you want.
