My view is that maybe she had never been around a PWS. Was probably a bit freaked out a bit internally, and did not know what to do. When I come across a person and a see their facial expressions when I am blocking I can sometimes tell this is their first time hearing and interacting with a PWS. My suggestion would be to ask her OP is this. Ask her has she had any interactions with a person with any type of speech disorder? Or you can say that I have a speech disorder and that disorder is referred to as Stuttering. Ask the follow up question. Was the fact that I am a person who stutters made you decide to end our date early? I am guessing she has not been around a PWS. Keep in mind two things OP. First. Stuttering is a hidden disability. Walking out in public you cannot tell who is a PWS and or is not a PWS. Secondly, OP, in a world of about 8 billion people, stuttering accounts for 3 to 4% of the global population. A very small number.
