The following conversation took place with one of my friends while discussing about a theory.
Me: I am right (about some theory).
Friend: No, you are wrong.
Me: (After giving it a deeper thought) Well, I see your point. I may be wrong also. But the reason behind my such thinking is that......
As you see I used the structure "my such thinking" in the conversation. I felt uneasy using that structure and somehow it did not feel fluent or right.
Is this grammatically correct? Does an alternative like "The reason why I think like this is..." or "The reason of me thinking like this is..." sound better?
