[speaker001:] Excuse me, can you do me a favor?
[speaker002:] Sure.
[speaker001:] Where's the busiest street of this city? I am a stranger here.
[speaker002:] You mean the seventy seventh? It's not far from here. You can walk there.
[speaker001:] Well, we are so tired today. Can you tell me which bus I should take?
[speaker002:] Bus No. 12.
[speaker001:] Thank you so much.
