Speaking for myself…
I’m afraid I disagree.
That’s one way of looking at it. However…
As far as I’m concerned…
Personally…
Could you explain what you mean by..?
Not necessarily.
I couldn’t agree with you more.
Definitely / Absolutely / Precisely
Could you say that again?
No doubt about it.
As I see it…
Sorry, I’m afraid I didn’t catch that.
That’s not always true.
Sorry, I didn’t get the question.
I see your point, but…
In my view…
Sorry, could you rephrase that?
For me…
Could you repeat the question, please?
