I'm awfully/terribly/so/extremely sorry, Mike. I forgot to bring you the tape.
Never mind. I'll use it tomorrow.
I'm sure you can have it tomorrow.

Sorry, honey. I've lost the key.
It's nothing. It's not the first time anyway.
Oh, come on. I won't be that silly again.

I beg your pardon? I didn't quite cach what you said.
All right. I'll repeat it.
Thank you very much.

Please excuse me for a while. I've got to go and have a look at my baby. It won't be long.
Certainly. I'll be waiting for you here.
It's very kind of you.

I'm sorry to have kept you waiting so long.
That's OK. What made you so late?
I was tied up with some urgent business.
I see.

I'm going to bring my kids with me. I hope you won't mind.
Not at all. I love kids, you know.
It's very nice of you.

Forgive me for interrupting you.
It doesn't matter. What's it?
I've got two questions to ask you.
Go ahead.

I'm afraid I've taken too much of your time.
It doesn't matter. I'm not so busy anyway.
Thank you very much.

Ouch, my foot.
Sorry about that. Are you all right?
Yeah, Do be careful next time.
I certainly will.

Did you bring my novel?
Oh, no. I forgot again. That was stupid of me.
Oh, well. You'd better bring it to me tomorrow.

A thousand pardons for having given you so much trouble.
Not a bit of it. I hope you can undersand what I've explained.
Yes, thank you.

I really feel bad about that, John.
No harm. Next time try to do it better.
I sure will.

Sorry to have lost your name card.
Don't worry. I'll let you have another one.
It's very kind of you.

Oh, my fault for breaking your pen.
Let's forget it. That can happen to the best of us.
You're so considerate.

I apologize for what I've said just now.
Don't think any more about it. And I do appreciate your concern.
I hope we can understand each other better in the days to come.

Please accept my apologies for not going to your party.
That's perfectly alright.
I had to take my little sister to hospital, you know.
Of cause, that's the most important.

I've got to apologize for troubling you  so much.
There's no reason to apologize for such a trifling thing.
Do drop in on me when you're in town.

I must beg to apologize for the delay.
Apologies are really quite unnecessary. We haven't really started yet.
Really? That's good.

I really owe you an apology for having lost your letter.
Please don't blame yourself.
I'll write another one.
It's all my fault.

I can't tell how sorry I am for giving you such a fright.
There's no need for you to worry. We're quite alright.
Really? Then I can set my mind at rest.
