> Although, sometimes people ask me a question where I have to work out in my head what the answer is and it feels weird to sit there in silence for 15 seconds as I do so. I've had to train myself to actually respond in this situations "let me think about that for a second". Because although the silence is awkward it is way better than rambling off and getting something wrong or having someone interrupt your train of thought by trying to ask again or saying something else before I've actually had time to think about it. For that last part, I've also found it helps if you make really exaggerated "thinking gestures" (look up with a very quizzical expression on your face, tap your had, stroke your chin, etc.).
