A stutter doesn’t mean someone has less to say. Wait for it.

A stutter affects the delivery of a sentence, not the sentence. The thought is finished and waiting; what is hard is the mechanical business of getting it out, which has nothing to do with how smart or how sure somebody is. Finishing their word for them takes the sentence away and says you had somewhere better to be.

Keep your eyes and your patience steady and let them arrive at their own word. No helpful guessing, no nodding them along faster. If you are the one who stutters, you are allowed to take the time the sentence needs.
