A2 (theater)

Okay kiddo, so you know what a theater is right? It's a big room where people can watch plays, movies, or other performances.

Now, the letter "a" in theater refers to a specific area of the stage. It's called the "stage right" area, which means it's on the actor's right side if they are facing the audience.

So when we say "a2" in theater, that means a specific actor needs to be in that stage right area during a scene. They might have to move around on stage, or maybe they have to stand still in that spot and do something important for the scene.

Basically, "a2" is just a fancy way of telling the actors where they need to be on stage at a certain time so that the audience can follow the story and enjoy the play!
