You are not right. Let's discuss it. Write to me in PM, we will communicate.

I do not doubt it.

I think, that you are mistaken. I suggest it to discuss. Write to me in PM.

Bravo, your phrase simply excellent

I apologise, but, in my opinion, you are not right. Let's discuss. Write to me in PM, we will talk.

I can not take part now in discussion - it is very occupied. I will be free - I will necessarily write that I think.

You are not right. I am assured. I can defend the position. Write to me in PM.

Excellent

I think, that you are not right. I can prove it.

It is a pity, that now I can not express - I hurry up on job. But I will be released - I will necessarily write that I think.
