[HerenIstarion]

Orc: Good morning, sir
Sam: Good morning, sir
Orc: There is no room enough for two to pass, let me step aside for you, sir!
Sam: Oh, no sir, you pass first, give me a pleasure!
Orc: Ah, sir, but how can I, please you pass!
Sam: I'm indeed honoured, sir, but let me make way for you!
Orc: No sir, please, you've been walking all that way up and must be tired, and for me it have been easy walk down the stairs, please you pass!
Sam: I see you are indeed a perfect gentleman, but sir, please go first as I see you are carrying some weighty load!
Orc: Oh, it's not heavy at all, kind sir, and besides, it's a short walk for me, and I see you've been travelling from afar, do be kind to proceed first...

After forty minutes of left-to-right a-dancing and bowing and polite muttering things finally begin to develop:

Orc: Arrgh, you crazy woolly-footed animal, why couldn't you just go along! I'll kill you!
Sam: Oh yeah? I've asked you to move on hundred times as if it was one, are you dumb or deaf, you oversized horned nutter?!
