Hey! I’m a stuttering college student as well, there’s a ton of people in the same boat as you because of the pandemic. If you have access to this kids email through a class forum or something I don’t think it would be weird to reach out and say you really liked it, maybe if applicable you can ask to play together? Otherwise I find the easiest way to make friends is sitting next to people in class or the dining halls, stuttering sucks but hey we get by through every other aspect of life with it so we can get over the hump of making friends too!
