My least favorite end to a sentence is "and why" because it just turned a 5 second question into a minute and a half.

It means you have to respond in full sentences which means at least five words.

I used to copy the sentence format all the way down the paper.

How many people would number all the homework problems on the side of the paper before you started solving. Just so you could convince yourself that you were working without having to think.
