要請教英文達人關於在電話對話...多謝！

1）Sorry, he is not around. / He is not in his desk. (should I use Desk as his 位子？）
比較 Proper 或禮貌一點的英文, 想註明他會很快回到位子:
Excuse me, he is not at his desk, but I guess he will be around soon. Please leave your number or message and I will advise him to get back to you as soon as possible.

2）如果他行開落咗樓下吸煙， 很快就會回來。應該怎麽說？
Excuse me, he is not around but he will get back in a minute. Shall I ask him to call you back upon his return?

For case (1), you can say:

Sorry, he / she is not at his seat at the moment but will be back soon. You may call him / her after a while. =]

(if the caller says "thank you" for your answer, you should reply "you are welcome" (=唔駛客氣))

For case (2), you can say:
Sorry, he / she is not at office but will be back soon. You may call him / her after a while. =]

(if the caller says "thank you" for your answer, you should reply "you are welcome" (=唔駛客氣))

"Sorry, he is not around for the moment."
"He's not out of office right now. He will be back in a minute. May I take a message for him/her?"

This is more polite. (And I think you don't necessarily need to tell the others that he/she is smoking.)

1. Don't say he's not IN his desk. Should say "He's not AT his desk"

2. Yes, never tell that "he went smoking"!!!

1）Sorry, he is not around. / He is not in his desk. (should I use Desk as his 位子？）
請問有比較 Proper 或禮貌一點的英文嗎？我想註明他會很快回到位子。

1. he's not here but he's coming back...

2.he/she is smoking down stairs,he/she is coming back.
