I think the fact that you are even asking this is a great sign of your intentions. I get blocks all the time and it can be terribly frustrating. You know exactly what you want to say, but your brain and mouth decide that's not going to happen. Honestly I think it really depends on the person. For me personally, I find that rhythm is a huge thing and if something throws me off I have to start it all over again. But at the same time sometimes that reset is exactly what I need. Long story short I think the way you handled it was totally fine! I appreciate that you didn't just try and say the word, but the whole sentence. Tone and body language is huge, and it sounds like you were very friendly and understanding, and at the end of the day that's all we're looking for! Great job!
