I have my reasons to openly stutter. I used to be covert but I'm trying to be more open these days because I noticed what my face does when I try to get through blocks so hard. An angry face even though I'm not angry. If you were eating with a fluent person and he said "this food is great" followed by his angry face, you'd think he's mad and you'd be right. But if you were eating with someone who openly stutters and he said "this food is g-g-great", you'd think he likes the food or being nice and you'd be right. My problem is, when I try to be covert, I sometimes sound like the asshole fluent guy. So now I disclose that I stutter and I consciously try to do prolongation or repeat every time I feel a block coming up. This way, I block less and when I block "angrily", I get to explain that it's my secondary behavior.
