Treat her like you would anyone else. You know, being patient and respectful. You said in another reply that you feel bad and want to help her. Thank you for the compassion, but we don't need to be patronized. She's not a little puppy you need to save, she's been dealing with this her whole life probably and she's holding down this job just like everyone else. My suggestion is try to get over it. Despite the fact that stuttering can be shitty and hard, we all have our problems and this is hers. Be patient, be normal, and that's the best thing you can do. Looking at her like a helpless little pup isn't going to help anyone. Having that said that, thanks for coming here and asking!
