Thank you so much DocV for confirming this.
I wonder if there is any possibility in the way you say "Yes, okay" that makes the listener think we are going to help. I ask because in the book "Work on your accent", written by Helen Ashton and Sarah Shepherd, published by HarperCollins, it is said "Give the response "Yes, okay", but make it mean three completely different things."
- Would you mind helping me with the washing-up?
1. Yes, okay. (I'd be happy to help.)
2. Yes, okay, (I'd really rather not, it's boring, but I suppose I should.)
3. Yes, okay. (Anything to stop your constant nagging)
Along with these comes a recording with 3 different intonations.
Until now, I've always said "Not at all" if I am willing to help. But when I read this, I am confused because of the word "yes". So it must be the intonation or the way we speak that may change "yes" into "no"?
