Dude I feel you. Don't know why I'm going to tell you this, but the part about how we react to the pitfalls got me thinking about the worst encounter I've ever had with a stutter. Some D-bag was with a friend of mine in high school that I was talking to at a party. I stumbled on some words that werent even that bad, and he immediately started mocking me and called me retarded. I told him that if he keeps doing it I'd hit him as hard as I could. He kept going, and I gave him one last warning. He said "D-d-d-dude, I s-s-swear I'm not..." And at that point I hit him as hard as I could in the chest. I heard a crack. He hit the ground like a sack of shit, and I was asked to leave the party. Turns out I broke one of his ribs and he got a minor concussion from when his head hit the tile floor. I felt so goddamn good after that.
