My brother "no longer stutters". That's what he tells everyone. He "cured" his stutter. He can even manage fluency in conversation. But he employs so many tricks and workarounds and loopholes that it's clear, at least to me, that he's just lying to himself and has instead merely gone covert. That is not a cured stutter, it's a hidden stutter. A ton of stutterers are covert stutterers, so we shouldn't try to judge whether or not someone is a stutterer based on how they sound at the time. If you've ever been covert, you know you mostly spend the majority of your energy trying to hide it and not much energy on saying the things you actually want to say. It can be without the feeling of embarrassment (if the covert stutterer is actually successful at being covert--not all are), but still has the feeling of not being able to express yourself, of being insular and internal, and of avoiding situations and people. Basically, whenever you hear someone say they no longer stutter... except sometimes... they are still a stutterer. They've just reframed it in their mind to make themselves more comfortable with it, and that's okay.
