I tell all my friends and family to please finish my word/sentence if I get stuck too long. Most don't and those that do, don't do it often but it's such a relief to me. I can get stuck for so long I give up. During this time, I'm hit with incredible frustration of not being able to say what I want, it puts any conversation on pause, kills any punchline and is embarrassing even in front of my brother or wife. When someone helps me with a word, I'm suddenly able to get it out and continue speaking. It's a huge help and much preferred over just staring waiting for me to finish. Your example you give as a possible solution would upset me personally. I would feel interrupted. If you helped with the word and let me finish then gave your input, that would be great.
