Professor, I do not mean to upset you, not at all, but a two-hour lecture is way too long.
In fact, I can barely stand one.
When your voice seeps into my ears, I feel like I'm in an airplane, economy class, on the sixth hour of a fourteen-hour flight, having left my moisturizer at home so my hands and face feel really, really, really dry. And when I breathe in, the oxygen feels weird, like it's there but I want to faint because it is off and won't give me the satisfaction an inhale promises right before it crosses the threshold into a breath.

Again, I do not mean to upset you, not at all.
But these seats are made of fabric, and the ground's fucking carpet.
