Even when the subway isn't crowded it still feels crowded. Why? Because any time a woman sits next to me on the train, I have to lean over to the side to make room for her wildly flailing elbow. I wonder if I fidget that much. Why are women always fidgeting? What is in that bag that they need to get at the moment their behinds hit the seat?
By the way, I'm ALWAYS mindful of my elbows. It comes from sitting down to eat with a large family. When eating at a table with a big family, you always need to make sure you kept your elbows in lest someone say to you "Flying somewhere?"
Elbows are pointy and dangerous and if you're sitting next to me in the subway, please keep yours away from me.
