如果对方喋喋不休，自说自话，而你又有别的想法，不如这样打断对方：

I understand what you're getting at, but (I'm just not interested/I just can't /it just won't be possible) at the moment.

我了解你所说的事情，只是我现在（不感兴趣/无法去/不可能去）。

或者直呼其名来强调语气

Look, Michael, I'm sorry, but it's just not going to be possible at the moment.

迈克尔，实在抱歉，但是现在确实不可能。
