I felt a bruise on my backside, right where my jeans meet my skin. I wondered if I backed into another doorknob, or table or a car-as I am known to do. I slide my hand around to get a better feel and try to comfort myself when I feel a bump. I run to the bathroom, pulling my jeans down slightly and peering at what is a huge bump on my backside. I am devastated as I knew I had a date later that evening and would hope my bump would not be revealed. I showed it to my coworker asking her if she could tell what it was, thinking it was a pimple. She laughed at me and said we don't get pimples on our backs! Its probably a bite.
