It's a funny conundrum because if people don't understand it, when stutterers say something as an aside, they typically go fluent easier, then as they get back to what they were saying, they may stutter again or feel a little relief from disclosing it but either way, that may start that whole idea about nerves because they hear you go fluent and there is something about not bringing attention to it that is more admirable to others. I've had others seem upset that I mentioned it telling me "it's the 20th century, not the middle ages" or something and someone telling me I don't need to and really shouldn't disclose it every chance I get like it's a big deal. I was caught off guard by the person reaction but it made me realize I relied on disclosing it like a crutch to make myself feel better and I believe it is much better not to feel like you need any sort of crutch. It became it's own self fulfilling prophecy oddly enough where I began stuttering anxious to just disclose it to find fluency after. It was odd and I didn't come to terms with it until that guy told me that disclosing it wasn't something I should do. He didn't realize I did it for myself more than others, to calm my down but I never needed to. I never do now. It was just something that became an unnecessary habit so I have to warn about that and I genuinely felt better not disclosing it after. It builds up it's own confidence seeing that I never had to. Their reaction is pretty cool too. That, coupled with just going fluent from being comfortable either way seemed to really make people feel good with me. The thing I can't stress enough is not caring about it and disclosing it might jeopardize that honestly because words are powerful to our minds. I know it may sound weird but saying things that remind us of something tends to keep the feelings around so talking about it is a kind of sign to our body that we worry over what others will think and that is what I think need not be the case because our minds like to assume the worst when it doesn't have to.
