My female English professor was going over a writing process in which instructions are written out in-depth, and her example was brushing your teeth.
Amongst the sample questions we could discuss as instructables were "Do I spit or swallow," "How far do I put it in my mouth," "how can I avoid a gag reflex," and "Is the head hard or soft?"
She was able to get through the lecture without a smirk.
I wasn't. Nor was my class.
