Depends entirely on who is roasting me. If my close friends are laughing I find that it really helps (I have told them that I don’t mind when close friends laugh at it) because it makes me stop and think ‘what the fuck is wrong with me’ and then I can talk fine after that. If it’s someone I don’t like or don’t know I won’t have them laughing at me. Would either ask them what they’re laughing at or just explain I have a stammer
