Honestly, the second one sounds so much more fitting but the examples are fascinating. Why would stuttering make someone feel more comfortable? And yet...I can kind of understand what you mean, like we must give them attention in the moment. It reminds me how I can get others to stutter slightly when i speak over them and they want to finish but wait..say again, wait, say again, stuttering as if there mind hasn't decided yet whether to carry on or not. But they have nothing stopping them from continuing on I believe where as with us it's a physical blockage of some kind. Or mental but actual stoppage whether we want to continue or not. This quick re-evaluation concept sounds very fitting but lets think...is it the case in all instances? Could we think of anything where it may not be so.
