I fucking love it when I’m struggling and people finish it for me. Idk why people don’t personally. like I just wanna get the word out and move on. Granted my stutter is not that band anymore at all. so if someone were to finish my word it would be 1-2 times in an entire hour long conversation. I could see how it’d get annoying if it was every other word. I would say good rule of thumb. If you don’t know them wait unless you get a “prompt” so mine is “what’s it called” if I say that please tell me what it is called. If you begin to form a friendship just ask. We know that you know we stutter.
