I have a family member that is incredibly smart but thinks &#x27;on the hoof&#x27;, in the middle of a sentence he&#x27;ll just freeze and go &#x27;umm&#x27;. I&#x27;m always tempted to finish the sentences but I&#x27;ve learned to bite that back and wait, usually the wait is more than worth it. Some people can form their thoughts and then spit them out fully formed in one coherent stream, others are confronted with their own words as input when they speak them and will adjust their thinking in real time. Both can lead to new insights and I wouldn&#x27;t immediately say that someone sounds &#x27;stupid&#x27; for pausing in the middle of a sentence and doing some inner processing, especially not if the outcome is good stuff.
