I noticed how, at work, while talking to customers on the phone, I talk quite fast and I am sometimes asked to repeat myself. On normal conversations, I guess it depends on who I'm talking to and the setting. If I'm sitting down talking to someone without looking them in the eye (just chilling, watching cars drive by and so forth), I talk normally, but if I'm looking them in the eye, I talk fast to make it end faster, I suppose. Also, I suppose I talk fast to hide my teeth. I'm getting braces in ten days, and I hope it'll truly help me be more confident.
