In my opinion...
The way I see it...
If you want my honest opinion....
According to ( person x)...
As far as I'm concerned...
If you ask me...
Asking for an opinion：
What's your idea?
What are your thoughts on all of this?
How do you feel about that?
Do you have anything to say about this?
What do you think?
Do you agree?
Wouldn't you say?
Expressing agreement：
I agree with you 100 percent.
I couldn't agree with you more.
That's so true.
That's for sure.
(slang) Tell me about it!
You're absolutely right.
Absolutely.
That's exactly how I feel.
Exactly.
I'm afraid I agree with James.
I have to side with Dad on this one.
No doubt about it.
(agree with negative statement) Me neither.
(weak) I suppose so./I guess so.
You have a point there.
I was just going to say that.
Expressing disagreement：
I don't think so.
(strong) No way.
I'm afraid I disagree.
(strong) I totally disagree.
I beg to differ.
(strong) I'd say the exact opposite.
Not necessarily.
That's not always true.
That's not always the case.
No, I'm not so sure about that.
Interruptions：
Can I add something here?
Is it okay if I jump in for a second?
If I might add something...
