Yes, really. And I have faced it. We can communicate on this theme.
I to you will remember it! I will pay off with you!
I can not recollect.
I think, that you are not right. I am assured.
You are not right. I can defend the position. Write to me in PM, we will talk.
What for mad thought?
Quite right! So.
Excuse, that I interfere, but, in my opinion, there is other way of the decision of a question.
You joke?
Certainly. I join told all above.
I join. And I have faced it. Let's discuss this question. Here or in PM.
Willingly I accept.
In it something is and it is good idea. I support you.
Excuse, not in that section.....
I am final, I am sorry, but it is all does not approach. There are other variants?
Many thanks for the information. Now I will know it.
I apologise, but, in my opinion, you are mistaken. I can defend the position. Write to me in PM.
Takes a bad turn.
And what, if to us to look at this question from other point of view?
You are not right. Let's discuss. Write to me in PM.
In it something is. Earlier I thought differently, many thanks for the information.
Excuse, I have thought and have removed a question
