Does his more-open stuttering make you feel uncomfortable? Maybe your laughing is just an automatic way you’re responding to something in him that you aren’t comfortable doing? This happened to a friend of mine the first time she went to a stuttering support group meeting. Everyone was just openly stuttering and she wasn’t ready for it. She hides. She tries not to stutter and when she was in that situation, she just laughed. Not to be mean, but just because she couldn’t process what she was experiencing.
