Generally I don't have a problem with stuttering but it still comes out. My worst experience was a few months ago when I got a phone call about a job application. The lady asked what previous experience I had and I could NOT get it out. I actually hung up, and I was in the car with my mom so she heard this. She told me to call her back immediately and say that my phone just ran out. Whether she bought it or not she let it slide, but throughout the entire conversation I could barely get words out, and when she asked for my email I actually spelled it out because I was too afraid of stuttering again. Few moments in my life were as embarrassing as that one. But on the plus side, I actually got the interview.
