Dear Prof lemming,
I'm being deployed to the Middle East soon. Remember how you teased me that I really should sit down and read the textbook rather than just reading the index? Well, I've thrown the book in my bag. It's a long flight and I'lll try to read it then. If nothing else, it might help me get some sleep.
I should be laughing - he's trying to be funny - so why do I want to cry?
