“Im laughing about my friend”

“Im laughing about my friend” hello everyone. I hear lots of people say that people laugh about a stutter, and I haven’t noticed it a lot- except when 1 context. often when I speak to 2 people, I have to admit it often only happens with ‘small minded‘ people, one of them starts laughing, I looked at them strange and they say “aha sorry im laughing about my friend not about your stutter” like really believable when the only moments I’ve seen you laughing is when I start to stutter. I don’t care if people laugh about my stutter (as in I disregard them), but my bullshit antenna is very active in these parts lol. it really just sounds like shifting responsibility
