i'm a new member 'n' i'm happy joining in
2 tell the truth, i'm asked to look 4 english refusal expressions 'n' i'm lost
so please can you help me?
Without more context:
No, thank you.
Thank you but I am already doing something.
It is a very kind invitation but I am engaged at that time.
You are very kind to ask me. I am afraid/I am sorry, I will not be able to accept.
Do these help?
