You know what I think, I think you should always go for that joke or always tell that story. Of course we have to focus on breathing and talking a little bit slower to people, but if your "friends" are the ones who blow you off and don't see interested in what you said then I would suggest not even wasting time with them and move onto people who DO want to hear what you have to say. Getting excited for us means that we stutter more and that's already difficult in itself, but don't let a few bad experiences kill who you truly are on the inside! Work on it and we'll get through it together, also could you describe the impact stuttering has had on your social circle?
