Let me off?

[zhengl_2000]

Example:

I was in a party. The host asked everyone to sing a song but
I am not good at singing and my voice is not good either.
So I said" let me off."

What I meant is let others sing not me.

what is the best way to say in this kind of circumstance?

I'd rather not
I got a sore throat (headache can work too)
My mother died while she was singing
My religion forbids singing.

Or you can simply burst out crying and run to the restroom.

Here's the phrase you're looking for,

Count me out, please. :D There's also I'll pass or I'd like to pass (on this one). :D

The opposite of count me out is count me in. :D

"Let me off the hook" would also work. :wink:

=====================================

Maybe my example was not what I really want to describe.

what i meant is that sometime people ask you to do sth.
you are reluctant to do.

Like at a party that people there are all friends , one guy said:"
Zhengl , sing an English song for us". I waved my hand and said" No, No
x????????? xI am not good at singing."

What should I say here x???????x ?

And what does it mean:
Let me off this time.

Friend: Zhengl, sing an English song for us.
Zhengl: I would rather not, thank you. (I'm not a great singer / I'm too shy.)

Let me off the hook
Imagine a fish on a fisherman's hook. The fish says, "Let me off (the hook) this (one) time. Let me go free; I don't want to be on your hook. I know I bit your hook (i.e. I made a commitment), but now I don't want to commit myself. I don't want to do it; I want to be free."

All the best, :D
