You can immediately tell who is a friend and who is ~~a terrible person~~ someone you don’t want to spend anymore time around. Quick example 1: You’re talking to a coworker (before they know you stutter), you stutter, they wait and let you finish your thought, you keep talking and are friends after many years, friend. Quick example 2: You are talking to a coworker (before they know you stutter), you stutter, they interrupt you, laugh at you and ask, “Woah! What the hell is that? Why’d you make that face??” You don’t talk to them again and are so much better off for it, Enemy. Both of these situations happened to me personally and I honestly think it is really cool we all have a real time litmus test to sus out the good people helps quite a lot in my opinion!
