Loo laugh

I just entered a public toilet when I heard a voice from the other room
-Voice: hi there!
-Me ( a bit annoyed) hello
-Voice: how are u?
-Me:(frustrated): Am fine
-Voice: what r u doing?
-Me: the samething that you are
-voice: can I come over?
-Me (irritated): I am rather busy
-Voice: hmm look I'll have to call you back later, there's an idiot from the other room answering all my questions
