How do you answers?
1.- you have set a time to meet with your errand boy in order to give him some important documents. The errand boy is always on time. You arrive late.
You says:........................................................................................
Errand boy says: It’s fine. Don not worry.
2.- you have to pay your maid. You know she needs the money urgently, however, you don’t have cash and forgot to go to the bank.
Maid says: could you give me my salary please?
You says :.......................................................................................
3.- your secretary has left a correspondence on your desk. You were very preoccupied and did not notice it. You get mad at her because you haven’t found it.
You says : where the hell did you put those papers!?
Secretary says: on your desk, sir.
You says : ..........................................................................................

1. I'm so sorry I'm late.

2. I'm really sorry but I forgot to go to the bank. I'll do it first thing tomorrow.

3. I'm sorry, I didn't see it.

P.S Stop using third person 's' with 'you'. It's 'you say'!
