Seeing double!

Robin 1: What are you looking at?
Robin 2: I might have asked you the same question!
R1: I was just wondering if there were any squirrels about!
R2: Well, I haven’t seen one today.
R1: But you shouldn’t be here, I was here first and you know how territorial us robins are and you’re far too near me!
R2: What are you going to do about it?
R1: Just buzz off!
R2: Do you think we look like bookends?
R1: Don’t change the subject, just go!
