Yes, it hurts. The person I'm talking about was a guy from Chile. We were waiting in line at a festival and I was talking and having a good time with strangers (I went there alone), until the guy struggled to say his name and one of the others hit him with the "forgot your name or something?". The guy with a stutter was hurt, I could tell by his expression, so I said "Be respectful. Of course he knows his name." Then I told him "I stutter as well. I know what it's like." but he proceeded to stay silent. I admire him for wanting to enjoy a festival, going ALONE and even trying to make friends. Unfortunately he came across an asshole, but I'm glad I was there for him.
