좀 조용히 해!

I'm in a cab now... travelling back home.
Cab uncle is super friendly; keep chatting with me from road names to new housing estates... I know he's just feeling bored and wanted someone to chat with him.

I'm trying my best to keep awake through our conversation. I just wish he knows I don't feel like uttering a word, especially when I started teaching and talking since 9am this morning till now...
