Being asked to repeat yourself is the absolute worst

Being asked to repeat yourself is the absolute worst There have been a countless amount of times where I was able to speak clearly, but then the person I’m talking to asks me to repeat it, because either it wasn’t as clear as I thought or they simply didn’t hear it, and now I’m stuck with my mouth open trying to get the words out of my mouth. It’s like I know exactly what I want to say and I say it the best I can only to be asked to repeat and now it’s a disaster. Does this happen to anyone else?
