I've noticed many people say not to complete a stutterer's sentence. This might be true for many but not for all. Every stutterer is different. I for one actually like it when people complete my sentences for me and so do some of my stuttering buddies. It takes a big weight off our shoulders. Of course we don't like it when people try to "guess" words. For example, if I go like, "Let's go to the mmmm...", I'd be offended if you were to say "Movies? Mall? Market?Huh?". But if you do know what I'm about to say(Let's go to the movies) then I'd actually like for you to complete my sentence for me and break my stutter. So you'd say, "Ok, let's go to the movies then." Of course, you wont know what I'm going to say all the time. In that case, simply smile and wait for me to complete my sentence. You can say something like, "It's okay. Take your time." or something along that line depending upon how close you are to that person. That helps us kind of relax. But like I said, it's different for different people. Anyway, I'm glad there are still people like you who are considerate to us stutterers. Good luck.
