The whole 'you forgot your name?' Thing is so tiring. I used to not correct because I didn't want someone to feel bad because usually it's not done maliciously and they don't know that I've a stutter. Now I correct people and tell them I've a stammer, they always look embarrassed and apologise but I don't feel guilty about that. Maybe us people who stutter are more empathetic, but I cannot think of a reason someone would say that, like no matter the context it's a jab at that person, whether it's friendly or not. I realise that stuttering isn't something that people come across every day, but there are so many reasons why someone struggles with their name. There is zero excuse, I believe, to say something like that, especially to someone who you do not know.
