Identifying someone

Liz      : Hi, Raoul! Good to see you!

            Where's Maggie?

Raoul  : Oh, she couldn't make it.

             She went to a concert with Alex.

Liz       : Oh! Well, why don't you go and talk to Julia?

              She doesn't know anyone here.

Raoul  : Julia? Which one is she?

             Is she the woman wearing glasses over there?

Liz      : No, she's the tall one injeans.

            She's standing near the window.

Raoul  : Oh, I'd like to meet her.
