怎么用英语说：我刚才说到哪了？ 怎么用英语说：我刚才说到哪了？ I am interrupted for a while when I am talking with someone, then I want to resume our conversation,but I forget what I have talked about, so I ask my friend who I am talking with to remind me. How to ask? "where did I talk about?" "What did I talk about?" "Where was I just now?" or something better?
