I feel this. While I'm struggling to talk, cause I want to express what I think in a conversation, people sometimes talk with someone who's passing by, interrupting me shamelessly. I feel broken inside tbh. Everyone must have lived this, but I think it's harder especially for a stutterer. When I don't feel like calling out the person, I just stop talking. Btw they don't notice, even if I was explaining something directly to them, their problem anyway. This type of person doesn't deserve my effort to talk
