I laughed at a kid with a stutter at subway
Why would you laugh at someone with a stutter?
The kid embarrassed himself by stuttering his name.
It's terrible to make fun of or laugh at someone because they have trouble speaking. You should not have made that kid feel bad because of his stutter. You should try to be more accepting of people in the future.
Who cares? He's a loser and wasn't quick with his words. It's not that bad.
But it's really mean to do and you probably made this kid feel worse about himself. In the future you should just ignore people's stutters and move on.
