Have I snapped?

Today, I made my advanced class write "I will indent every paragraph" ten times. Have I snapped? Not sure, but I do know that every day I tell them to indent, and every day they don't. I threatened them that if they don't indent tomorrow, they'll write 15 sentences, and so on and so on. Is it really so hard?

I am continually baffled by how minds work. This morning, while introducing a reading on the Titanic, I asked the class to tell me what they knew about the Titanic. One student asked, "the headache?" Huh? What on earth does a headache have to do with a giant ship sinking nearly 100 years ago? The ship wasn't named The Migraine. I'm stumped.
