I don’t always have an answer ready so whenever I don’t and I need time to think of an answer I use delaying tactics.  This way I don’t give my conversation an awkward silence.

To learn how to do this.

Use delaying words like: I’m sorry can you repeat that? What do you mean by “reflect question” ? That’s a good question. So you are asking about “rephrase question”? Just to make sure I got that correctly…” rephrase question “ I’m not really sure but… At the top of my head… I’m thinking.. What’s the word for that? How do you put it? Let me think for a moment. Smile. 

Use your common sense and don’t overuse a tactic. I hope you find these useful.
