Several years ago on Halloween I dressed up in a gorilla mask, furry hands and an long black robe and went to a bar where I knew my youngest sister would be that night. I then made it my priority to stalk her all night long not saying a word so she couldn't recognize my voice. I even followed her into the rest room which made her really nervous because she couldn't tell if it was a man or woman in the costume. It wasn't until bar time that I finally took my mask off to reveal who I was. She about wet herself from laughing so hard when she saw it was me! She said she never thought I would do something like that to her!
