I think a classmate may stutter covertly

I think a classmate may stutter covertly Hey everyone, I had an interesting realization today. Around a week ago I was in class (college, relatively large about 70 students), and someone asked the professor a question and I thought that I picked up on a mild stutter. Naturally, as another PWS, I figured it would be nice to meet this person. Unfortunately I had an exam coming up that I was not prepared for, so I dipped out of class as soon as it let out to I could get to cramming. I figured I would try to talk to him another time. Today he asked the professor a question again, and while it still seemed like he was stuttering a bit, but I realized he may be trying to stutter covertly. I know we as PWS can sometimes pick up on things that the average person would not, and I think this might be one of those cases. Now I'm in kind of a tough spot, because if I were to just approach him casually after class that may out him and that's certainly not something I want to do. But asking a random stranger to come talk with me in private would also come off as very strange (I am much more fluent than I was in the past thanks to speech therapy so there's a good chance I wouldn't stutter while asking him about this). I've only met a handful of other people who stutter in my life, and in every case we each knew each other stuttered beforehand, so I'm not quite sure how to go about this now. So I guess this post is kind of dual purpose, sharing an interesting thing that happened to me and asking for advice on how to proceed, lol. Thank you for taking the time to read my post. P.S. I noticed several distinct prolongations and repetitions in his speech, to the point where the professor did actually make an "it's okay" type remark about it, so I'm relatively confident it wasn't just a fluke or something, but I also second guess myself a lot lmao
