Did you notice how I answered each question in yesterday's lesson? Here's the first part of each of the four answers:
- No, not at all.
- Yes, definitely.
- Yes, unfortunately it does.
- Yes, many times.
After answering with these short phrases, I then explained my answers in more detail, using full sentences.
I think this is a nice technique that you could try. Start with a short "yes or no" answer (e.g. yes I do, no we don't, yes it certainly is...), and then explain your answer fully. Perhaps this technique will give you a few extra seconds to think before you give your full answer.
