I'm a stutterer, not as bad as I used to be but the phone is still fairly hard. I have a job where the phone is a preferred way of communication, so it's scary sometimes. A professor called me up the other day on my office phone and he had a pretty bad stutter. As a stutterer, it was easy for me to feel what he felt while he was talking. I was almost in tears as he was talking, especially when he started the conversation saying "please bear with me, i have a very bad stutter". Being patient is not our strong sense for sure, but it needs to be!! The professor was able to say everything he wanted to say and I got him all squared away though!
