Well, before I start, I just want to say that a 'story' is vague, there are hundreds of ways to tell a story, speaking it, in a song, a book, a play script, a TV show, these all tell stories. But I'm going to assume you mean 'story' as in novel, short story (etc).
A story/ novel, is meant to be read, so you have to describe everything:
Joe enter the office with his shoulder slumped. "Good morning." He said in a sad and tired voice.
"Hi, Joe, what's wrong?" Maggie asked from her seat at the front desk.
He closed the space between them and collapsed into the chair across from her. "I'm just exhausted."
Although Maggie didn't think it was her place to ask, she didn't like seeing Joe so beaten down. "Troubles at home?"
A play script is meant to be seen. So all you need to write are stage directions (you can be either detailed or vague with these, every playwright is different) and dialogue:
Scene 2: The next day. Joe's office. his secretary, Maggie, sits at the front desk.
Joe: [sadly] Good morning.
Maggie: Hi, Joe. What's wrong?
Joe: [sits] I'm just exhausted.
Maggie: [carefully] Troubles at home?
There are different formats for play scripts. At least, I know there is in Canada and America, so it's worth googling the correct format for your country.
Hope this helped!
