My brother is crazy. The teacher doesn't know what my brother is talking about in class.
Can you be more specific? Do you know why he is crazy? Is my brother learning English? You all said he was crazy. If he doesn't speak English, his brother is really crazy. What sense of superiority does he have? Jinda has one for each person. Let's go to the hospital. Don't delay my brother's illness, but it's good to find the right medicine!
