Don't sit on me, lady!

So I discovered that I have issues with personal space. I was waiting at the train station today and it gets pretty crowded, it being rush hour and all...but man, some people need to learn the concept of personal space. Don't get me wrong, I'm cool with sitting next to a stranger in a cinema, but this girl literally sat soooo close to me at the train station that it was just creepy. She plopped down right beside me and I could feel her ass on the side of my thighs....damn...the weirdest thing is, it was totally normal for her. She continued sitting there and talking to her friend next to her while I looked very uncomfortable. Crazy woman...I moved of course. Personal space, people!
