Men on the subway: you take up more than your fair share of space. Close your legs. You don't need three feet between your knees. Particularly when it means you're taking up the better part of 2 other seats.
My personal space is important too. I like having a distinct area that is mine. Your leg is not welcome. Why don't you put your legs together when someone sits next to you? I make room when you sit down next to me. In fact, like most women I politely and embarrassedly compact myself.
Perhaps men's wide legs are a birthright. Leg-spreading certainly starts young. One day I spotted an empty seat between a 50 year old woman and an 11 year old boy listening to his ipod. His legs were spread and clearly in the seat bubble next to his, but I figured he's young enough that he thinks I'm a real grown-up that deserves respect. So, I sat down. Like much older members of his gender, the kid did not move his leg. I sighed and settled in for the discomfort.
So, guys, please while we're all stuck on the train together, close your legs. It's a small, crowded island we live on. Don't make it feel even tinier and denser than it already is with your far apart legs. There's nothing wrong with crossing your legs. You don't look silly. In fact, you look respectful and aware that you're sharing the subway with others. Thanks.
