P.S. Some quick advice if you’re talking to a person who stutters:
Relax. Be patient. Don’t rush them. Don’t be anxious for them. Don’t “help” them by completing their word for them. (It’s NOT helpful!) If a stutter starts, let them find their own way through it. Chill. You’re good. It’s all good. Show them you’re listening and attentive, and you don’t mind them taking the time they need. Give them your patience, your attention, and your acceptance.
