What Time Do You Usually Go To Bed?

Thor	Wake up Kim Sook! You are dead on your feet today.
Friend	Sorry, I had a late night last night.
Thor	Well, you are not paid to sleep on the job.
Friend	Don't give me a hard time Mr Park. You know I work well.
Thor	Yes, usually you are excellent. Sleepy operators are dangerous to everyone though.
Friend	I'm usually in bed by 11pm, but my child was sick all night.
Thor	Oh, I'm sorry. Let me know if you need some time off
Friend	Ah, don't worry about it. Just go.
Thor	Oh, you are no help at all.

Jung	What time do you usually go to bed ?
Choi	Often it's around 1am before I hit the sack, or maybe later if we go out to a club. How about yourself ?
Jung	Me? Oh I'm nearly always in bed by 11pm. I'm no night bird.
Choi	I guess you get up pretty early then ...
Jung	Well yes. I rise at 6am and do some exercises.
Choi	Exercises !!? It takes all my will-power to get out of bed. I'm not civilized until about lunch time.
Jung	Ah, I don't understand guys like you. Burn the candle at both ends and you will be an old man at forty.
Choi	Relax, we're just different, that's all. It takes all kinds of people to make the world go around.
Jung	OK, OK, but quieten down a bit at night, will you ! You woke me up at 3am this morning.
Choi	Oh, sorry about that. Maybe I had a few too many drinks last night.
