If the girl is as amazing as you claim she is, then something like a stutter shouldn’t be a dealbreaker between your friendship or even relationship with them. And the same can apply to your friends. Everyone has their quirks and imperfections and that’s completely okay. If you’re best friends with your coworkers then you shouldn’t feel afraid of them finding out such things. If you’d rather them not find about your issue through actual stuttering/blocking, then you should let them know directly that you have a bit of a speech problem. If any of them are going to badmouth you or even have an issue with your apparent stutter then are they even friends to begin with? True friends wouldn’t have their minds closed over another having a problem they can’t help with. Keep your head up, Redditor.
