Last tuesday after work I went to Walmart. While I was looking at shoes I heard a very inoffensive, agreeable group of people mobbing their way through the store. The next thing I know is that a some guy has shoved his hand in my face to introduce himself,  ugh. He wouldn't read my body language to leave me alone and I was afraid to tell him directly to go away, yet, how could I be afraid and think he would punch me in the face? I have experiences with drunk guys where they try to pick you up and as soon as they realize you are not interested they turn away, non-violently. One minute it is hey girl, the next they are no longer in your face and ready to kill.
