Mine isn’t too bad since I don’t have many really negative experiences part from the usual “Did you forget your name” or something like that. When I was 14, I was doing woodwork at school and as part of woodwork we have to do theory, questions about wood and how to use it to make things and stuff like that. At one point, the teacher asked a question. I don’t remember what the question was, but I answered “measurements” without stuttering at all. She heard me but asked me to repeat myself since there were people talking when I answered. This time when I tried to answer I blocked so badly on the m and spent what felt like 30 seconds just going “mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm…”. It felt really awkward and the whole time I could hear my classmates saying it and my teacher going “it’s ok. He’s got it. He’s got it.” which didn’t really help. After about 30-40 seconds I kinda just gave up cause it just wasn’t gonna come out and she said it. I felt really really embarrassed and humiliated. It was just not a nice feeling at all. It was horrible
