Are U Crazy?

Last night, i was at my friends house, when his house mate came in and asked him, if he attended class the last time when it was raining heavily.
And he answer him by saying, " are you crazy? in that rain! "

i laughed to myself as i realized that he had just made a Rhetorical Question as a conclusion.
He didn't even answer his house mates first question directly, but answered him using a rhetorical question that gave him an answer that obviously he didn't attend class that day because it was raining too much.

it's funny how we use most of the skills of Critical Thinking in our everyday lives.
