A Carter who gets mad if you say their name wrong and then proceeds to embarrass themselves in front of the whole class
I said 'Carter' wrong. He got mad and tripped over his own shoes in front of the class.
I called him 'Carters' and he ran to the front of the class and cried.
I said 'Carter' like it was a brand. He said, 'That's not how you say it!' and fell over.
