My stutter comes in waves, I can go from extreme disfluency to very rarely being 100% fluent. Even in my worse times I can hide it to a fair degree by being mostly quiet and only saying things I'm sure I can say without trouble. I understand you being annoyed at people thinking you're fluent or "gotten over your stutter". I dislike the latter more because it only produces disappointment in myself as well as others when I start to stumble over my words again.
