Super Proofreader Strikes!

Today, in one of my classes, I returned a long lost hat to its rightful owner. I watched as he took out a felt pen and wrote a message on the inside of the hat hoping to deter anyone from taking it in future. The message read, "Touch this and your dead".
In retrospect, perhaps I should have had a quiet word to him about a less-threatening method of protecting his hat. However, my proofreading instincts overcame all else and I whipped the pen and hat back out of his hands, so as to add the crucial missing apostrophe and letter 'e', so that the message correctly read, "Touch this and you're dead".
Obsessive about proofreading? Who, me?
